Abstract :
We present the design and simulation results for a photonic integrated circuit (PIC) that performs in-channel and broadband radio-frequency self-interference cancellation. The PIC removes interference by modeling channel effects and inverting a known interferer prior to combining it with the corrupted signal. We present key simulation results showing that the PIC can cancel extremely wideband interferers by ~20 dB. The PIC performance can be improved by reducing signal attenuation and nonlinearities. We plan to fabricate the PIC on a hybrid silicon-on-insulator III-V evanescent photonic platform.
