Abstract :
We demonstrate an 83-nm flat gain-bandwidth gain-clamped semiconductor optical amplifier-Raman hybrid amplifier for coarse wavelength-division-multiplexing (CWDM) access networks. Four channels of 2.488-Gb/s CWDM signals were amplified and the input dynamic range for 1-dB bit-error-rate power penalty exceeds 17.3 dB.
