主　　题：Demultiplexing Optical filters 

摘      要：A demultiplexing scheme based on semiconductor optical amplifier（SOA）and optical filter for optical time division multiplexing differential quadrature phase shift keying（OTDM-DQPSK）system is proposed and investigated *** only a common half baudrate electrical clock modulated 33%duty cycle return-to-zero（RZ-33）optical clock signal as pump,this scheme is cost-effective,energy-efficient,and integration-potential.A proof-of-concept experiment is carried out for the demultiplexing of a 2×40-GBd OTDM-DQPSK ***-free performance is demonstrated,and the average power penalty for both channels is about 3 dB.
