Biasing a Diode Laser at the Self-Mixing Crossover Improves Immunity to Backreflection

Not Accessible

Your library or personal account may give you access

Abstract

The adverse effects of back-reflected waves on a diode laser used as a transmitter can be substantially mitigated if the current biasing is set at a specific value, the self-mixing crossover which can be found by a simple setup. A de-sesitization of the reflection effects by a factor of 25 dB has been observed.
