We demonstrate the photonic generation of an ultra-wideband millimeter-wave (MMW) signal (white-light), which covers the full W-band (75-110 GHz). A W-band photonic emitter (PE) with a wide 3-dB optical-to-electrical bandwidth (30 GHz, 80-110 GHz), constructed by integrating a planar quasi-yagi radiator for feeding the WR-10 waveguide-based horn antenna and a high-power near-ballistic uni-traveling-carrier...
The generation of optical millimeter-wave with frequency 8-tupling is experimentally demonstrated. 625-Mb/sec QPSK data transmission at 105-GHz (W-band) is achieved for the first time using the millimeter-wave generation technique and direct modulation of a NBUTC-PD.
By integrating near-ballistic uni-traveling-carrier photodiodes with planar W-band bandpass filters, the demonstrated devices under optical local-oscillator and intermediate-frequency signals injection can exhibit high internal up-conversion-gain (14.2 dB) with a high output photocurrent (19 mA) at W-band (100 GHz).
