Whispering-gallery mode based photonic RF receiver

We describe our recent achievements in the integration of narrowband photonic RF receivers and discuss their ultimate performance parameters. The best sensitivity and the spurious free dynamic range achieved in the current built of our coherent receiver approaches -145 dBm/Hz and 90 dB/Hz
^2/3
respectively. We plan to improve these values to -164 dBm/Hz and 105 dB/Hz
^2/3
in the next generation receivers, while keeping the 13.5 × 8.5 × 4.7 mm form factor intact.
