目前集成光路已有很大发展,然而某些光学器件仍难以进行单片集成,例如作在半导体材料上的光源和探测器、作在晶体上的光开关和调制等就是如此.它们只作为分立器件被使用.为了解决这一问题,已经制成了三维集成光路用的印刷电路板.三维集成光路的基本形式,是将一个光学印刷电路板和光学器件组合起来,而光学印刷电路板则是由光波导和垂直的光输入和输出部分组成的,各种光学器件在
At present integrated optical paths have been greatly developed, however, some optics are still difficult to monolithically integrate, such as light sources and detectors for semiconductor materials, optical switching and modulation on a crystal, etc. They are only used as discrete Devices have been used.To solve this problem, a 3-D integrated optical circuit printed circuit board has been made.The basic form of a 3-dimensional integrated optical circuit is a combination of an optical printed circuit board and an optical device, while the optical printed circuit board is Consists of optical waveguides and vertical optical input and output sections with various optics
