Abstract
Official abstract text for this publication.
A vertical cavity surface emitting laser (VCSEL) configured to operate in a gain switching regime includes a cavity that is terminated by reflectors at both ends for enabling a standing wave of optical radiation therebetween. The cavity comprises at least one quantum well, each of the quantum wells located at a position where a value of a standing wave factor for each quantum well is between zero and one, 0<ξ<1.
First claim
Opening claim text (preview).
What is claimed is: 1. A vertical cavity surface emitting laser (VCSEL) configured to operate in a gain switching regime, having a cavity that is terminated by reflectors at both ends for enabling a standing wave of optical radiation therebetween; the cavity comprises at least one quantum well, each of which is located at a position where a value of a standing wave factor ξ for each quantum well is between zero and one, 0<ξ<1. 2. The laser of claim 1 , wherein at least one of the reflectors at the ends of the cavity is a distributed Bragg reflector. 3. A pulse vertical cavity surface emitting laser (VCSEL) operating in the gain switching regime, the VCSEL comprising a cavity terminated by top and bottom distributed Bragg reflectors, and active layers inside the cavity consisting of some quantum wells whose positions in the cavity are detuned from the standing wave antinodes in such a way that the standing wave factor ξ for each quantum well is between zero and one, 0<ξ<1.
