ABSTRACT:
In an optical amplifier circuit for amplifying input signal light by the use of excitation light having polarized light component into amplified output light, an optical fiber doped with a rare-earth element amplifies the input signal light into the amplified output light. A light converter is coupled to the excitation light source and converts the excitation light into a converted excitation light having depolarized light component.
