    Abstract:The monodisperse colloidal NdF3 nanorods were synthesised via one-step thermolysis of Nd(CF3COO)3 3H2O in a hot trioctylphosphine oxide solution. The resulting product was characterised by Fourier transform infrared analysis, transmission electron microscopy and photoluminescence spectroscopy. The rod-like nanocrystals possess well shaped fenestral structures. Optical spectra exhibited the colloidal NdF3 nanoparitcles possessing typical Nd3+ ion absorption and photoluminescence emission. The emission cross-section of 4F 3/2 → 4I11/2 fluorescence transition was 2.12 × 10-20 cm2, and comparable with some laser glasses. Copyright ? 2013 Inderscience Enterprises Ltd.

    Abstract:A kind of cylinder-type electrode and high dynamic range X-ray streak camera has been optimally designed and developed. By improving the accelerating field, optimizing electronic optical system, the spatial and temporal characteristics of the electronic optical system is obtained with the modulation transfer function (MTF). By using the gold cathode (Au) and the large dynamic microchannel plate (MCP), the streak tube's dynamic range is further enlarged. Experimental test is carried out by Nd: YLF laser (8 ps) and dynamic scanning circuit, and the results show that the dynamic range is more than 1000, the time resolution is less than 14 ps, and the dynamic spatial resolution is over the 15 lp/mm. This indicates that the performance of the streak tube receches the design requirements and meet the demand of the ultrafast diagnostics. Meanwhile, the optimization direction and the program design is correct.

    Abstract:We present simulation results for a 5 Gb/s optically pre-amplified, differential phase shift keying communication system achieving -48.1 dBm (about 24.7 photons/bit) receiver sensitivity at 10-9 bit-error-rate and using an optical delay line interferometer made by ourselves with 1 bit delay as the demodulator. The system is also experimental tested and sensitivity of the receiver is -36.5 dBm (about 106.6 photons/bit). The experimental results have some penalty in sensitivity comparing to the results in the simulation because the 1 bit delay interferometer is sensitive to the environment such as temperature, tremble and so on. To our knowledge if the interferometer is well designed and optimized, the experimental results can correspond with the simulative results and an optically pre-amplified direct detection DPSK receiver with high sensitivity can be realized. ? 2013 Copyright SPIE.

    Abstract:With the advancement of high performance charge coupled device (CCD) in aerospace imaging detection, image quality is placed a high value. The importance of an ideal CCD working ambient temperature is realized with the deeply researching of the characters of CCD. A temperature controlling system based on multi-TECs is introduced deriving from the need to prevent thermally induced dark currents from becoming the dominate noise source. -65°C± 2 °C is the designed value for best function of the CCD used in our project. The principle and work mode of TEC are analyzed. An originally multi-TECs controller design is given for meeting this requirement as well as power and cubage. PWM control and linear control are actualized on two types of TECs according to different application mode. Below 10% current ripple is acquired and the temperature stabilization is below±0.6°C. The ambient temperature is achieved nicely in simulating CCD working cabin experiment stably and efficiently. ? 2012 IEEE.

    Title:Photonic bandgap via nonlinear modulation assisted by spontaneously generated coherence
    Author(s):Yao, Yin-Ping(1); Zhang, Tong-Yi(1); Kou, Jun(2); Wan, Ren-Gang(1)
    Source: Physics Letters, Section A: General, Atomic and Solid State Physics  Volume: 377  Issue: 21-22  DOI: 10.1016/j.physleta.2013.04.013  Published: September 2, 2013  
    Abstract:A four-level double-ladder atomic system with two upper states coupled to the excited state by a standing-wave trigger field is explored to generate photonic bandgap (PBG) structure. With the assistance of spontaneously generated coherence (SGC) from the two decay pathways, we can obtain single or double fully developed PBG when the trigger field is far away from resonance or resonant. While in the absence of SGC, the atomic medium becomes strong absorptive to the probe field, and therefore the resulting PBGs are severely malformed or even cannot be opened up. Numerical results show that the PBG structure is originated from the third-order cross Kerr nonlinear modulation between the probe and trigger fields. This mechanism differs from the recent schemes based on linear modulation. ? 2013 Elsevier B.V.

    Author(s):Duan, Jie(1,2); Xie, Xiao-Ping(1,2); Duan, Tao(2); Wen, Yu(1)
    Source: Guangzi Xuebao/Acta Photonica Sinica  Volume: 42  Issue: 9  DOI: 10.3788/gzxb20134209.1031  Published: September 2013  
    Abstract:In order to solve the three problems of terahertz optical asymmetric demultiplexer-cross phase modulation effect based all-optical exclusive-OR gate, which are that the strict demand of synchronization; cannot be applied in the situation of not return to zero signal input; the speed of exclusive-OR operation is limited by carrier recovery speed of semiconductor optical amplifier. An all-optical exclusive-OR gate was proposed which utilizes the structure of terahertz optical asymmetric demultiplexer and is based on four wave mixing effect, because of based on four wave mixing, this exclusive-OR gate can radically solve the mentioned three problems of terahertz optical asymmetric demultiplexer-cross phase modulation based exclusive-OR gate. This paper illustrates the principle of this exclusive-OR gate through theoretic analyse, and realizes the exclusive-OR operation for the input of 40 Gbps, return to zero signal; 80 Gbps, return to zero signal; 10 Gbps, not return to zero signal. The Q factor and bit error rate of exclusive-OR operation for above three kinds of input are 11.7, 2.4×10-18; 8, 1.1×10-10; 22, 1.3×10-40. And then, we analyse the influence on the quality of exclusive-OR output signal which is generated by change of parameter of main elements of terahertz optical asymmetric demultiplexer and temperature and dispersion effect. The feasibility and effectiveness of this exclusive-OR gate for solving the three problems of terahertz optical asymmetric demultiplexer-cross phase modulation based all-optical exclusive-OR gate are verified by theoretic analyse and simulation.

    Title:An all-optical multi-wavelength encryption system
    Author(s):Duan, Jie(1,2); Wen, Yu(1); Duan, Tao(2); Xie, Xiao-Ping(1,2)

    Abstract:In order to encrypt multi-wave input signals simultaneously, according to the analysis of the effect of light interference, we conclude that XOR encrypting operation can be realized by the interference of two coherent optical signals one of which is given pi phase shift before they combining. According to this conclusion, an all-optical encryption system which can be used in wavelength division multiplexing (WDM) system and encrypting multi-wavelength optical signals is proposed. This scheme achieves multi-wave length coherent optical signals and optical keys by direct electro-optics modulation, and achieves pi phase shift of multi-wavelength optical keys by phase shifter, then the XOR encrypting operation for optical signals can be realized by the combining and interferring of optical signal and key which have the same wavelength, and then the multi-wavelength encrypted result is output. The feasibility and effectiveness of this system are confirmed by the simulation of encrypting operation of 8 × 10 Gbit/ps WDM signals. The bit error rate (BER) and Q factor of encrypting output are 0 and 164, respectively. Moreover, this paper analyzes the Q factors of encryption output at different duty cycles of input signals. When the duty cycle of input signal is smaller than 0.43, the Q factor of encrypted result is about 164.

    Abstract:In order to realize the all-optical encryption for multi-wave and ultra-high speed, an all-optical encryption scheme is proposed, which is based on pockels effect of LiNbO3 waveguide and optical-time-division-multiplexing (OTDM) in LibNO3 waveguide. The coherently ultra-high speed plaintext and key are generated by OTDM in LibNO3 waveguide and the XOR operation of optical plaintext and key are achieved by direct light interference. The feasibility and validity of this scheme is verified by simulative experiment at 8 x 80Gbps with wavelength interval of 2nm. ? 2013 Copyright SPIE.

    Abstract:The multi-mode combination timer device can receive the GPS\GLONASS, No.1 BeiDou and loran-C at the same time. Since the multiple external frequency sources are introduced for the system, it is necessary to manage and monitor it. The wavelet decomposition atomic time algorithm is used to weight average the external reference signals in the wavelet domain, and the integrated time scales are obtained. The disciplined clock technology is employed to the time scale for calibrating the clock; the results indicate that the system can achieve fast timing and the complementary advantages of all kinds of resources. ?

    Abstract:A reflection mode digital holographic microscope with light emitting diode (LED) illumination and offaxis interferometry is proposed. The setup is comprised of a Linnik interferometer and a grating-based 4f imaging unit. Both object and reference waves travel coaxially and are split into multiple diffraction orders in the Fourier plane by the grating. The zeroth and first orders are filtered by a polarizing array to select orthogonally polarized object waves and reference waves. Subsequently, the object and reference waves are combined again in the output plane of the 4f system, and then the hologram with uniform contrast over the entire field of view can be acquired with the aid of a polarizer. The one-shot nature in the off-axis configuration enables an interferometric recording time on a millisecond scale. The validity of the proposed setup is illustrated by imaging nanostructured substrates, and the experimental results demonstrate that the phase noise is reduced drastically by an order of 68% when compared to a He-Ne laser-based result. ? 2013 Optical Society of America.

    Title:Parallel on-axis phase-shifting holographic phase microscopy based on reflective point-diffraction interferometer with long-term stability

    Abstract:Parallel on-axis two-step phase-shifting reflective point-diffraction interferometry for holographic phase microscopy based on Michelson architecture is proposed. A cube beamsplitter splits the object wave into two copies within the two arms. The reference wave is rebuilt by low-pass filtering with a pinhole-masked mirror. Both object and reference waves are split into two beams by a grating in a 4f imaging system; thus, two interferograms with quadrature phase-shift can be acquired simultaneously with the aid of polarization elements. The approach has the merit of nanometers-scale phase stability over hours due to its quasi-common-path geometry. It can make full use of camera spatial bandwidth while its temporal resolution is as fast as the camera frame rate. Phase imaging on microscale specimen is implemented, and the experimental results demonstrate that the proposed approach is suitable for investigating dynamic processes. ? 2013 Optical Society of America.
