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 $< $300 MHz while locking to a $\sim$0.5 million Q microring with $\sim$19.6 GHz free spectral range (FSR), improving to $< $100 MHz level after locking to a $\sim$1.5 million Q microring with $\sim$25.2 GHz FSR. The locked lasers were modulated with dual polarisation 16-QAM signals with $< $1 GHz guard-band between two channels, and the MRR locked DFB lasers achieved similar performance to commercial external cavity lasers in the coherent communication system.
期刊介绍：
The Journal of Lightwave Technology is comprised of original contributions, both regular papers and letters, covering work in all aspects of optical guided-wave science, technology, and engineering. Manuscripts are solicited which report original theoretical and/or experimental results which advance the technological base of guided-wave technology. Tutorial and review papers are by invitation only. Topics of interest include the following: fiber and cable technologies, active and passive guided-wave componentry (light sources, detectors, repeaters, switches, fiber sensors, etc.); integrated optics and optoelectronics; and systems, subsystems, new applications and unique field trials. System oriented manuscripts should be concerned with systems which perform a function not previously available, out-perform previously established systems, or represent enhancements in the state of the art in general.
