Abstract

A filter design based on Vernier microrings and wideband directional couplers is proposed for ASE noise suppression in next generation DCI applications. We demonstrate a ~40 nm FSR-free filter with > 20.5 dB average ER and 3dB-BW of ~ 75 GHz, achieving wavelength-independent performance and full tunability with a maximum tuning temperature of ~75 K.
