Ultranarrow-linewidth self-injection-locked tunable blue GaN DFB laser
Georges Perin, Laurent Lablonde, Marco Rossetti +4
In this work, we demonstrate an ultra-narrow linewidth self-injection locked distributed feedback (DFB) diode laser emitting at 452 nm, achieving an intrinsic linewidth of 170 Hz w…

Sub-20 kHz low frequency noise near ultraviolet miniature external cavity laser diode
R Kervazo, A Congar, G Perin +6
We present a compact InGaN fiber Bragg grating (FBG) semiconductor laser diode operating below 400 nm in the single-mode emission regime. This compact coherent laser source exhibit…
