Abstract :
A serial type, C+L-band hybrid amplifier based on a single pump laser diode is proposed. Dispersion management and gain equalisation among C+L-band channels are realised simultaneously. Pump reflectors and double-pass schemes are used to increase the pump slope efficiency. The power variation is reduced from 6.5 to 0.2 dB among C + L band channels.
