Broadband high-brightness light sources based on semiconductor optical amplifier and superluminescent diode

摘要

It is experimentally shown that a semiconductor optical amplifier (SOA) ensures a significant improvement of output characteristics of a superluminescent diode (SLD). Using SOA based on (InGa)PAs SC DH (central wavelength - 1300 nm) in MOPA system with SLD as a master oscillator a CW output power of 50 mw ex SM fiber was obtained. The same SOA used as a combiner of its own ASE and red-shifted input SLD light signal permits obtaining the output emission with linewidth near 70 nm.
