ABSTRACT:
The present invention discloses a hybrid optical amplifier coupling a Raman fiber amplifier and a semiconductor optical amplifier, comprising: a laser diode generating and radiating a laser light for a Raman optical amplification; a wavelength division multiplexer passing an incident signal light and radiating a laser light radiated from the laser diode in a reverse direction of the incident signal light; and a gain clamped semiconductor optical amplifier amplifying an optical signal light radiated from the wavelength division multiplexer.
