We demonstrated near-ballistic uni-traveling-carrier photodiode based broadband photonic transmitter-mixers with quasi-Yagi radiators fed horn antennas. 100GHz wireless transmission with date rate as high as 12.5-Gb/s via bias modulation under high photocurrent (20mA) has been achieved.

Record wireless data transmission of 31.4 Gbps within 7 GHz license-free band at 60 GHz is experimentally demonstrated using adaptive bit-loading OFDM modulation. Adaptive bit-loading OFDM also enables extended fiber transmission distances beyond 5km.
A W-Band Photonic Transmitter-Mixer Based on High-Power Near-Ballistic Uni-Traveling-Carrier Photodiode (NBUTC-PD) for 1.25-Gb/s BPSK Data Transmission under Bias Modulation

We demonstrate W-band photonic transmitters-mixers, which are composed of near-ballistic-uni-traveling-carrier-photodiodes and quasi-Yagi antennas without integrating Si-lens. By utilizing it, data-transmission at W-band can be achieved under bias modulation of 1.25-Gb/s BPSK with 5GHz IF signals. (C) 2009 Optical Society of America

We show that optical up-conversion performs better than electrical up-conversion in simple IMDD-based 60GHz radio-over-fiber links. Feed-forward equalization improved the performances of both systems, enabling error-free transmission of 4 Gbps over 500m of single-mode fiber. (C) 2008 Optical Society of America
