摘要

Up and down frequency conversions in the range of 0.5-39.5 GHz are performed by using a Semiconductor Optical Amplifier-Mach-Zehnder interferometer (SOA-MZI) in a differential configuration as a sampling mixer. The authors show that increasing the sampling frequency by a ratio of 2.5 (from 7.8 to 19.5 GHz) improves the efficiency and the quality of the optical transmission of QPSK and OFDM signals...
