Abstract :
We demonstrate a low-phase noise frequency-tunable photonic source for generating 100 GHz W-band signals. The source offers up to twelve times optical multiplication by exploiting nonlinearities in MZM and FWM in UL-SOA. Wide frequency tuning (95-115 GHz) with average output power of -24 dBm @ 4.18 mA photocurrent and output power variations <;0.5 dB is demonstrated. The absolute phase noise of the W-band signals is measured to be <;-91 dBc/Hz at 10 kHz. By using an optical reference LO, the residual phase noise from the photonic source is confirmed to be even <;-103 dBc/Hz at 10 kHz offset.
