Paper Abstract

MicroPhotonic broadband RF signal processors utilize the capability of photons to perform true-time delay processing at very low loss that is unattainable by conventional electronic methods. In this paper, we present a novel MicroPhotonic interference mitigation filter architecture that utilises a CMOS Si photoreceiver/VCSEL array in conjunction with a true-time-delay multi-cavity optical substrate to realise an adaptive transversal RF processor with arbitrary response. Results show that the proposed MicroPhotonic structure can synthesize adaptive interference mitigation with a shape factor (ratio of the -40dB bandwidth to the -3dB bandwidth) as low as 2 and passband ripples less than 0.25dB.
