BROADBAND LIGHT SOURCE AND WAVELENGTH DIVISION MULTIPLEX PASSIVE OPTICAL NETWORK LIGHT SOURCE INCLUDING THE SAME CAPABLE OF GENERATING LIGHT OF BROADBAND BY USING TWO FABRY-PEROT LASER DIODES AND A TAP FILTER

摘要

PURPOSE: Broadband light source and wavelength division multiplex passive optical network light source including the same are provided to improve noise characteristic and to simplify the structure of the light source.;CONSTITUTION: A first fabry-perot laser diode(FP LD)(120) and a second FP LD(140) output light with defined mode spacing. A tap filter(160) passes or reflects a part of light from the first and second FP LDs. The tap filter transmits a part of light from the first FP LD to the second FP LD and transmits a part of light from the second FP LD to the first FP LD. The FP LDs receive light from the tap filter and outputs wavelength locked light.;COPYRIGHT KIPO 2012
