REFLECTIVE OPTICAL SOURCE DEVICE

摘要

The present invention relates to an optical source device. The optical source device includes a mode converter for optical combination with optical fiber, a semiconductor light amplifier which is combined with the mode converter, amplifies an optical signal inputted through the optical fiber, and an electric field absorption modulator which is combined with an optical amplifier and modulates and output amplified optical signal. The semiconductor optical amplifier and a light absorption modulator include heaters which can control temperature.
