Abstract

To improve the performance of Si photonics-based wavelength locker, a new configuration for a compact wavelength locker with two grating couplers (GC) and a Mach-Zehnder interferometer (MZI) filter used in light source modules was proposed. Simulation results showed that the proposed two GC structure provides 1.4 times higher peak coupling power with over 10 μm mounting tolerance and the monitored values for the MZI filter system was enhanced over three times. This shows that there is feasibility on developing this topology for a compact wavelength locker in the short reach coherent communication.
