We demonstrate a novel technique for photonic generation of few-cycle millimeter-wave (MMW) pulse using a WR-10 waveguide and near-ballistic unitraveling carrier photodiode (NBUTC-PD)-based photonic-transmitter-mixer (PTM). A 2.5-cycle MMW pulse is generated by simultaneously exciting the PTM optical port with 100-GHz optical MMW sinusoidal signal and the intermediate-frequency (IF) port with...
We demonstrate a remotely up-converted and distributed 20-Gbit/s wireless on-off-keying (OOK) data transmission link at the W-band that uses a near-ballistic uni-traveling-carrier photodiode (NBUTC-PD)-based photonic transmitter-mixer. This device consists of an active NBUTC-PD integrated with a planar passive circuit for feeding the intermediate-frequency (IF) modulation input and extracting the...
By combing high-modulation-depth (160%) photonic 124GHz MMW sources with NBUTC-PDs for remote (>;25km) generation, 6dB power enhancements and 14.4dBm saturation power are achieved as compared to NBUTC-PDs operated under sinusoidal excitation.
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...
We demonstrated near-ballistic uni-traveling-carrier photodiode based broadband photonic transmitter-mixers with quasi-Yagi radiators fed horn antennas. 100 GHz wireless transmission with date rate as high as 12.5-Gb/s via bias modulation under high photocurrent (20 mA) has been achieved.
A liquid crystal spatial light modulator that operates from the ultraviolet (350 nm) to the mid-infrared (2400 nm) is described. The modulator is suitable for shaping the electromagnetic wave form of multioctave optical pulses.
