摘要： The present invention is intended to provide a compact and simple optical semiconductor device that reduces crosstalk (leakage current) between light receiving elements. According to the present invention, since a back surface electrode is a mirror-like thin film, crosstalk to an adjacent light receiving element can be suppressed, thereby reducing a detection error of a light intensity. By disposing a patterned back surface electrode or by disposing an ohmic electrode at the bottom of an insulating film over the whole back surface, contact resistance on the back surface can be reduced. By using the optical semiconductor elements with a two-dimensional arrangement and by using a mirror-like thin film as the back surface electrode, crosstalk can be reduced. By accommodating the optical semiconductor elements in the housing in a highly hermetic condition, the optical semiconductor elements can be protected from an external environment.
摘要翻译：本发明旨在提供一种紧凑且简单的光学半导体器件，其减少光接收元件之间的串扰（漏电流）。根据本发明，由于背面电极是镜面状的薄膜，因此能够抑制与相邻的受光元件的串扰，能够降低光强度的检测误差。通过设置图案化的背面电极或通过在整个背面的绝缘膜的底部设置欧姆电极，可以降低背面的接触电阻。通过使用具有二维排列的光半导体元件和通过使用镜面状的薄膜作为背面电极，可以降低串扰。通过将光学半导体元件容纳在高度密封状态的壳体中，可以保护光学半导体元件免受外部环境的影响。

摘要： A wave transmission medium includes an input port 3-1 and an output port 3-2. A field distribution 1 and a field distribution 2 are obtained by numerical calculations. The field distribution 1 is a field distribution of the propagation light (forward propagation light) launched into the input port 3-1. The field distribution 2 is a field distribution of the phase conjugate light (reverse propagation light) resulting from reversely transmitting from the output port side an output field that is expected to be output from the output port 3-2 when an optical signal is launched into the input port 3-1. According to the field distributions 1 and 2, a spatial refractive index distribution is calculated such that the phase difference between the propagation light and reverse propagation light is eliminated at individual points (x, z) in the medium.
