Optical transmitter module and wavelength division multiplexing light source using the same

摘要

An optical transmitter module for creating an optical signal having the same wavelength as an incoherent light inputted thereinto is provided. The module includes a substrate, a multi-layer crystal growth layer including a first area for amplifying the incoherent light and the optical signal and a second area for creating an optical signal having the same wavelength as the incoherent light amplified by means of the first area, and an electrode unit for independently injecting currents into the areas of the multi-layer crystal growth layer. A light generated at a broadband light source is spectrum-sliced and injected into the optical transmitter module so that a wavelength division multiplexing light source is realised.
