Abstract
Conference Title: 2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR) Conference Start Date: 2017, July 31 Conference End Date: 2017, Aug. 4 Conference Location: Singapore, Singapore We report, for the first time to our knowledge, on the self-injection locking of chirped InAs/InP quantum-dash (QDash) lasers with ∼6.5 nm locked Fabry-Perot mode tunability, in the L-band wavelength emission. The modes exhibited ∼30 dB side mode suppression ratio (SMSR) with ∼8–9 dBm mode power. Generally, the locked mode SMSR and tunability is found to be limited by the L-band amplifier amplified spontaneous emission noise. This demonstration paves the potential deployment of widely tunable self-locked broadband QDash laser modes as sub-carriers' generator in the next generation high capacity fiber based and wireless optical networks.
