Abstract:
1. A dual-port broadband light source comprising: a first gain medium for generating a first amplified spontaneous emission (ASE); a second gain medium for generating a second ASE; a first beam splitter connecting a first light path to a second and a third light path, for splitting the first ASE at a first ratio and, outputting the split first ASEs to the second and third light paths, and further outputting the first ASE received from the second light path to the first light path; a second beam splitter connecting the first light path to the second light path and a fourth light path, for splitting the second ASE at a second ratio, outputting the split second ASEs to the second and fourth light sources, and outputting the second ASE received from the second light path to the first light path; a first reflector positioned in the first light path, for reflecting input first and second ASEs; a second reflector positioned in the second light path, for reflecting input first and second ASEs, wherein the first gain medium is positioned between the first reflector and the first beam splitter in the first light path and the second gain medium is positioned between the first reflector and the second beam splitter in the first light path.
