Paper Abstract

An unbalanced Mach Zehnder interferometer (UMZ) is used here for up-conversion of a microwave subcarrier, with IQ modulation at 30 and 200 Msymb/s. Both QPSK and QAM-16 are investigated, and a low BER of 10-9 is demonstrated after detection of the up-converted microwave subcarrier for an optical power of -1dBm delivered by a directly modulated laser diode.
