ABSTRACT:
Provided are an optical module used in a high-frequency optical communication system, and an optical receiver module, an optical transmitter module, and an optical repeater module for receiving, transmitting, and repeating an optical signal in a high frequency band. The optical module includes a silicon substrate, the optical fiber, devices, a signal transmission line, and an oxidized porous silicon layer. In the silicon substrate, a V-shaped guide groove for arranging an optical fiber is formed. The optical fiber is installed in the V-shaped guide groove and used as a path through which an optical signal is input or output. The devices are mounted on the silicon substrate to receive, transmit, or repeat the optical signal. The signal transmission line electrically connects the devices. The oxidized porous silicon layer is formed at least between the silicon substrate and the devices to prevent signal loss.
