Device
Electro-optical comb generator and a photodiode applied to generate multiple synchronized sources in multiple bands and sub-bands of the desired spectrum. Electro-optical comb generator and a photodiode applied to generate multiple synchronized sources in multiple bands and sub-bands of the desired spectrum.
Spectrum
W-band (92-114.25 GHz), D-band (130-148 GHz) for this demonstration
Novelty
A single oscillator is used to generate an optical comb that produces electrical signals at multiple frequencies in multiple bands and sub-bands when the o-comb is converted to an e-comb by a photodiode.
Performance
The wideband phase noise performance in the >30 kHz region coincides closely with the low phase noise performance of the driver making the technique potentially suitable for wideband mm-wave transmission. Multiple sources derived from the o-comb forego requirements for frequency multipliers for enhanced phase noise performance.
