Abstract
Two architectures with quadrature modulation in a generic InP platform are proposed for realizing frequency-modulated continuous-wave (FMCW) LiDAR. Simulations are used to compare the architectures in terms of tolerance to optical imbalances, insertion loss, chip footprint, and ease of control. The parallel architecture is more resilient to imbalances (~0.82 dB power imbalance for 20 dB ER) than the cascaded architecture (~0.63 dB power imbalance for 20 dB ER).
