Abstract :
This letter presents experimental characterization of an integrated reflective electroabsorption modulator and semiconductor optical amplifier (REAM-SOA) device in the radio-over-fiber (RoF) context. Orthogonal frequency-division-multiplexing (OFDM) modulation condition optimizations have been carried out by varying the temperature, the voltage biasing of the modulator, and the current applied to the semiconductor amplifier.
