Abstract
We self-injection locked two free-running DFB lasers to two adjacent resonances of microring resonators (MRRs) to enhance the lasers frequency spacing stability. The frequency spacing stability between the two locked lasers was <300MHz while locking to a ∼0.5 million Q microring with ∼ 19.6GHz free spectral range (FSR), improving to <100MHz level after locking to a ∼1.5 million Q microring with ∼ 25.2GHz FSR. The locked lasers were modulated with dual polarisation 16-QAM signals with <1GHz guard-band between two channels, and the MRR locked DFB lasers achieved similar performance to commercial external cavity lasers in the coherent communication system © 2024 IEEE.
