Spontaneous emission alteration in InGaAs/GaAs vertical cavity surface emitting laser (VCSEL) structures

Semiconductor Science and Technology, 1999
The spontaneous emission from vertical-cavity surface-emitting laser (VCSEL) structures consisting of an In0.2Ga0.8As/GaAs quantum well and AlAs/GaAs distributed Bragg reflectors (DBRs) was systematically investigated as a function of reflectivity of DBRs, energy difference between the excitonic energy and the cavity mode and emission wavelength ...

Investigations of vertical cavity surface emitting lasers (VCSEL) resonant cavities by photoreflectance spectroscopy

SPIE Proceedings, 1995
Avancees) Dept OPT-CENG17, rue des Martyrs, 38054 Grenoble Cedex FRANCEABSTRACFPhotomodulated reflectance spectra of vertical cavity surface emitting laser (VCSEL) wafers havebeen measured between 9K and 300K. Structures used are grown in the A1GaAs based system, and aretop surface emitting ones centered near 800 nm, with a lambda cavity, similar to ...

Optical pumping using chirped pulses of a vertical-cavity surface-emitting laser (VCSEL)

2007 Quantum Electronics and Laser Science Conference, 2007
We study the response of a VCSEL after optical pumping using pulses with varying quadratic chirp. The data are in good agreement with a microscopic rate approximation model.

Fabrication and applications of lift-off vertical-cavity surface-emitting laser (VCSEL) disks

SPIE Proceedings, 2002
Vertical cavity surface emitting lasers (VCSELs) are prepared by standard epitaxial crystal growth techniques on GaAs substrates. The VCSELs include AlGaAs distributed Bragg reflectors (DBRs) and selectively oxidized AlAs or AlGaAs current confinement/optical wave-guiding layers.
