METHOD AND APPARATUS FOR CONTROLLING REFLECTIVE SEMICONDUCTOR OPTICAL AMPLIFIER (RSOA)

摘要

A method and apparatus for controlling a reflective semiconductor optical amplifier (RSOA) are provided. The RSOA control apparatus sets a threshold current at which a light source starts to oscillate to be constant regardless of a wavelength of seed light by controlling a driving temperature for driving a RSOA, and adjusts an optical characteristic which is differently output for each wavelength of seed light to be constant by controlling a driving current.
