Abstract :
A photonic frequency up-conversion scheme based on the nonlinear polarization rotation (NPR) arising in a semiconductor optical amplifier (SOA) for wavelength-division-multiplexing(WDM) signals is proposed and experimentally demonstrated. Error-free simultaneous up-conversion of 4times2.5 Gbps WDM baseband channels with a 20-GHz local oscillator (LO) signal is experientially achieved in the whole C-band. Then the WDM up-converted signals are successfully transmitted over 20 km of single-mode fiber (SMF) with less than 0.8 dB power penalty. Both the radio frequency (RF) spectrum and the bit-error-ratio (BER) performance after electrical down-conversion have shown low distortion induced by the optical mixing process.
