Single longitudinal mode ridge waveguide 1.3μm Fabry-Perot laser by modal perturbation

Research output: Contribution to journalArticlepeer-review

Abstract

The authors introduce a cost effective technique which converts the multi-longitudinal mode output of a 1.3μm ridge waveguide Fabry-Perot laser into a single mode by creating modal perturbations along the length of the ridge. Up to 25dB side mode supression is measured on their first lasers.
