Eight-port optical routers are widely used in cluster-mesh photonic networks-on-chip (NoC). By using 24 groups of cross-coupling two-ring resonators, a 1-stage 8-port polymer optical router is proposed, which can optically route 7 channel wavelength data streams along definite path in two-dimensional (2D) plane. Under the selected 7 channel wavelengths, the insertion losses along all routing paths are within 0.02-0.58 dB, the maximum crosstalk of all routing operations is less than -39 dB, and the device footprint size is about 0.79 mm2. Then, a universal novel structure and routing scheme of N-stage cascaded 8-port optical router are presented, which contains 7N channel wavelengths. Because of the good scalability in wavelength, this device shows potential application of wideband signal routing in optical NoC.

本文根据部分相干光成像的理论,分析了光源的空间相干性及时间相干性对相衬显微镜成像质量的影响,并对相衬环同光源的形状及大小的匹配问题进行了讨论.结果表明,部分相干光照明将引起位相物体像的对比度下降.由于相衬环在一定程度上改变了非零频谱的特性,因此像面上的光强分布亦有所改变.如果对照明条件及滤波方式进行一些改进,相衬显微镜的成像质量将会得到改善.
