随着军用红外光学仪器的发展, 对红外光学镀膜元件耐环境性能的要求越来越高。以波段在 8～12.m的 Ge、ZnS、ZnSe镀增透膜样品为对象进行红外增透膜湿热雨林气候环境适应性研究。以外观质量、重量、光谱透射比等为评价指标进行环境适应性评价, 得出以下结果: 经过 3年湿热雨林气候环境试验, 红外增透膜出现了不同程度损伤, 损伤模式主要为变色和脱膜; 随着试验时间的延长, 变色越来越严重, 变色区域越来越大; 重量出现先减少后增加的现象, 光谱透射比出现少量下降; 经过 3年的湿热雨林气候环境试验后, 红外增透膜均已失效。

为开展 OLED显示器在热带雨林气候条件下的环境适应性研究，将 OLED显示器置于西双版纳试验站进行库内自然暴露试验，并定期对样品进行观察和检测。经过一年的暴露试验， OLED显示器表面出现针孔、黑点和膜 层脱落等现象，以及发光面积减小和亮度降低等性能衰减变化。研究发现， OLED显示器在热带雨林环境中长期受温度、湿度等环境因素的交变应力作用，其密封性遭到破坏，外界氧气、水汽等进入显示器内部，最终导致 OLED显示器失效。因此，要想进一步提高 OLED显示器在热带雨林环境中的使用寿命，关键在于改善 OLED显示器的密封性。

Switching-window in an interferometric configuration of a gain-transparent ultrafast nonlinear interferometer (gt-UNI) is investigated numerically. The phase change is observed in detail. To assess the performance of switching window, the integrated contrast ratio (ICR) is introduced. For the data pulse with the bit width of 6.25 ps and with the energy of 60 pJ, respectively, the ICRs in different situations are simulated using modified nonlinear Schrodinger equation (MNLSE) considering of the carrier depletion pulsation (CDP), carrier heating (CH), and spectral-hole burning (SHB). The results show that the maximum ICR is located at the optimum position of the semiconductor optical amplifier (SOA) that is determined by the width and energy of the control pulse.

A novel symbol overlapping optical fast frequency-hop code-division multiple access (FFH-OCDMA) system is proposed, and its bit error rate (BER) performance is investigated under consideration of avalanche photonic diode (APD) noise and thermal noise.

The theoretical and experimental results show that the system is apt to implement and has larger throughput.

Optical burst switching (OBS) is a promising optical switching technology. The burst assembly algorithm controls burst assembly, which significantly impacts performance of OBS network.
