Abstract :
The paper presents simulation results for laterally-corrugated ridge-waveguide distributed-feedback (DFB) semiconductor lasers emitting at 980 nm, along with measured results. The effect of the corrugation on the laser output characteristics is discussed. Almost 50 dB side-mode suppression ratio was achieved for the laterally-corrugated ridge waveguide DFB lasers fabricated using nano-imprint-lithography.
