Broad-area InGaAs-AlGaAs laser diodes emitting at a wavelength of 980 nm with dry-etched mirror facets are presented. The devices exhibit optical output powers up to 1.5W per facet at room temperature...
A Brief Note on Coherent Feedback in Semiconductor Lasers
Coherent Feedback Semiconductor Lasers
2010/12/15
Some aspects on coherent feedback in a laser diode are investigated. In particular, weak optical feedback is considered in the context of the feedback-induced frequency shift. In addition, the Lang-Ko...
