Patent ID: 7043116

Claim:
A dual-port broadband light source with independently controllable output powers, comprising: a first gain medium having two ends; a first input pump light for pumping the first gain medium so as to output a first amplified spontaneous emission through both ends of said first gain medium; a second gain medium having two ends; a second input pump light for pumping the second gain medium so as to output a second amplified spontaneous emission through both ends of said second gain medium; and a reflector disposed between opposite inner ends of the first gain medium and the second gain medium for reflecting an input of the first and second amplified spontaneous emissions, a first output terminal and a second output terminal arranged at respective outer ends of the first gain medium and the second gain medium; wherein the first and second amplified spontaneous emissions output from the first and second gain mediums are output to an exterior of the light source through the first and second output terminals.
