20-Gb/s on-off-keying wireless data transmission by using bias modulation of NBUTC-PD based w-band photonic transmitter-mixer

We demonstrated near-ballistic uni-traveling-carrier photodiode based broadband photonic transmitter-mixers with quasi-Yagi radiators fed horn antennas. By adopting a novel design in the intermediate-frequency (IF) port of such device, we can further extend the IF (bias) modulation bandwidth of NBUTC-PD to over 14GHz. Wireless data transmission with record-high on-off keying date rate as 20-Gb/s via bias modulation of such novel device has been successfully achieved.
