Spontaneous emission factor of a microcavity DBR surface-emitting laser
TL;DR: In this article, the spontaneous emission factor (SEF) of a microcavity distributed Bragg reflector (DBR) surface-emitting laser has been obtained theoretically to investigate the possibility of the thresholdless lasing operation.
Journal ArticleDOI
Spontaneous emission factor of a microcavity DBR surface emitting laser. II. Effects of electron quantum confinements
TL;DR: In this paper, a method for the theoretical analysis of the spontaneous emission factor (C factor) has been developed for microcavity distributed Bragg reflector (DBR) surface emitting lasers having various quantum-well active regions.
Proceedings Article
Spontaneous emission factor and lifetime of a microcavity distributed Bragg reflector surface-emitting laser with quantum-wire structure
TL;DR: In this paper, the spontaneous emission in a microcavity is controlled for considering future device performances of SEEDs, and a thresholdless lasing operation, coherent and low noise spontaneous emission light are proposed.
Proceedings ArticleDOI
Driving level dependence of spontaneous emission factor in microcavity DBR surface emitting lasers
TL;DR: In this article, the spontaneous emission factor (C factor) of a three-dimensional microcavity DBR SE laser has been obtained and it has been shown that the variable C factor provides a substantial difference in the L-I characteristic of a micro-avity SE laser.
