Wavelength tunable bidirectional optical wireless communication system based on self-injection lock

摘要

A wavelength tunable bidirectional optical wireless communication system based on self-injection lock includes one optical node and multiple optical terminals, wherein the optical node consists of a tunable filter and a self-injection lock system to replace the conventional optical amplifier while achieving an amplified optical power, increasing the modulation bandwidth, wavelength adjustment and reducing the linewidth of each wavelength, in a low noise criteria. The optical terminal is composed by a modulated retroreflector to achieve the purpose of lightweight and low power consumption.
