Wavelength locking of a Si ring modulator using an integrated drop-port OMA monitoring circuit KU Leuven
© 2016 IEEE. Silicon micro-ring modulators have the potential to enable energy efficient, high-bandwidth-density optical interconnects in CMOS compatible silicon technologies. However, their operation is highly susceptible to any thermal, laser wavelength or process variations and, as such, require a feedback control system for guaranteeing stable modulation. This paper demonstrates wavelength locking of a hybrid CMOS-silicon photonics ...
