In this paper. we analyse the beam propagation within the optical cavities of all integrated MicroPhotonic adaptive RF signal processor, and optimize the optical beam diameter and incidence angle that maximize the number of taps to realise high-resolution R F processor. Simulation results show that for a 1m-diameter collimated Gallssioll beam, 16 taps per cavity can be achieved for a 20mm-long cavity, and that there is no need for a diffractive optical element (DOE) to re- collimate the Gaussian beam within the cavity. The tolerance of the MicrnPhotonic processor to changes in optical cavity length which degrade the beam overlapping with the active areas of the photodetector elements, is also quantitatively analysed.
