We systematically investigate the bubble-induced performance degradation for underwater optical wireless communication (UOWC) with different bubble sizes and positions. By using different transmit and receive diversities, we investigate the effectiveness
本文提出了多谱线单纵模塞曼激光器理论,并根据氖原子的拉卡矢量模型计算了632.8nm He-Ne纵向塞曼激光器的振荡频率和光强,最后对所得到的结果进行了讨论.
采用时域有限差分法研究了硒化锌基底的抛物线型周期阵列仿生微结构的光学性质,重点分析了微结构阵列的周期、高度、占空比和形状轮廓等对反射率的影响,得到了有较好增透效果的结构参数。根据模拟参数进行两次干涉曝光制备掩模,采用反应离子刻蚀技术制备周期阵列微结构。通过场发射扫描电子显微镜对微结构的表面形貌进行表征,并采用傅里叶变换红外光谱仪在中红外波段分别对双面抛光、单面微结构的硒化锌片进行透过率测试。结果表明:单面微结构样品在2~5 μm范围内的整体平均透过率比双面抛光硒化锌基片提高了10%,在2.3 μm处的最大
In this paper, the current research of an underwater optical wireless communication (UWOC) network is reviewed first. A hybrid laser diode (LD) and light-emitting diode (LED)-based UWOC system is then proposed and investigated, in which hybrid cluster-bas
日本国际电信电话公司研究所采用将阴性型光致抗蚀剂与阳性型光致抗蚀剂同时以双光束干涉曝光的全新方法，研制成原理上一定从单波长振荡的分布反馈半导体激光器。

It is accidental, but interesting to celebrate the 10th anniversary of Chinese Optics Letters (COL)
after revival from the “most important” day in 2012, December 21, which is closely related to Mayan
calendar. The last decade sees the development of optic
