We demonstrate novel Si/Ge avalanche photodiodes based electrical comb-line generators, which can directly generate ultra-wideband (10 GHz) comb-lines and short-pulse. By using this device, 1.5Gbps error-free ultra-wideband short-pulse photonic wireless-linking have been successfully achieved.
We experimentally demonstrate an optical ultra-wideband (UWB) (75 GHz-110 GHz) fiber-to-the-antenna (FTTA) system using our developed W-band near-ballistic unitraveling-carrier photodiode (NBUTC-PD) based photonic transmitter (PT). 2.5 Gb/s and 1.5 Gb/s UWB-FTTA systems with 1,024 high split-ratio are demonstrated.
By using novel near-ballistic uni-traveling-carrier photodiodes (NBUTC-PDs) based W-band photonic transmitter and a mode-locked laser with a 10 GHz repetition rate, 2.5 Gbit/sec impulse-radio wireless data transmission at 100 GHz with 3.3 m maximum transmission distance have been demonstrated.
We demonstrate near-ballistic unitraveling-carrier photodiode (NBUTC-PD)-based V-band (50-75 GHz) optoelectronic (OE) mixers which can upconvert the V-band optical local-oscillator (LO) and intermediate-frequency (IF) signals. The optical LO and IF signals share a single erbium-doped optical fiber amplifier (EDFA) which means that the mixing performance of the device can be optimized by properly adjusting...
