Sampling rate influence in up and down mixing of QPSK and OFDM signals using an SOA-MZI in a differential configuration

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...
