ABSTRACT:
A Raman optical amplifier includes a fiber amplifier for Raman-amplifying an input optical signal to form a primarily-amplified optical signal, and a semiconductor optical amplifier for outputting a Raman pumping light of a predetermined wavelength adapted to Raman-pump the fiber amplifier, while amplifying the primarily-amplified optical signal to form a secondarily-amplified optical signal. A circulator allows the fiber and semiconductor amplifiers to communicate the lights and signals and operates with fiber grating, which acts as a filter, to output the secondarily-amplified optical signal
