Broadband light source with dual-port structure

摘要

A broadband light source (200) with a dual port structure includes a gain medium (210) pumped by inputted pump light (260,265) for outputting ASE light (270,275) through both terminals thereof, and a pumping section (230,235) for pumping the gain medium (210). The broadband light source (200) outputs ASE light (270,275), which is outputted from both terminals of the gain medium (210), to an exterior through first and second output terminals (250,255). <IMAGE>
