Not Accessible

Your library or personal account may give you access

Abstract

We present a tunable hybrid square/rhomb-rectangular AlGaInAs/InP semiconductor laser for ethylene detection. Single-mode lasing around 1.626 μm is achieved with a side mode suppression ratio above 30 dB and an output power over 1 mw.
