Abstract

We report on the design and simulation of an optical All-Pass Filter (APF) which is a passive photonic chip using a pulley-type, microring resonator (MRR) configuration using a Finite-Difference Time-Domain (FDTD) solver from the Lumerical MODE. The main challenge is to reduce optical losses. We analyze its main properties and performance by optimizing the parameters of the device that include (i) varying the gap, (ii) coupling length, and (iii) the ring radius. The data measured from the parameter sweeps are the optical transmission graphs. The main properties are free spectral range (FSR) and full width at half maximum (FWHM).  Several indications of optical losses were observed from the simulation graph results. The PIC design is fabricated using E-beam lithography.
