Abstract:
We demonstrate a Ku-band fully integrated microwave photonic generator (FI-MWPG) proto-type using a novel low-noise hybrid InP/Si3N4 comb laser based on the self-injection-locking mechanism. The FI-MWPG experimentally exhibits an ultra-narrow RF Lorentzian linewidth of 0.8 Hz and a stable frequency of only 16 kHz@5 mins.
