All-optical Regenerator Using Semi-reflective Semiconductor Optical Amplifier [PDF]
Journal of the Optical Society of Korea, 2006 We have proposed and theoretically verified an optical regenerator using a single semi-reflective semiconductor optical amplifier (SR-SOA). To explain the operation characteristics and the operation condition of the proposed opticalregenerator, the simplified gain model for the SR-SOA is introduced and confirmed by comparing the result of the SOA ...
