Vertical-Cavity Surface-Emitting Laser With a Chiral Nematic Liquid Crystal Overlay

open access: yesIEEE Photonics Journal, 2014
We demonstrate measurement results of the light emission of vertical-cavity surface-emitting lasers (VCSELs) with chiral liquid crystal (CLC) overlay (CLC-VCSEL). Two different CLC materials with different chiral-phase temperature range are presented and

Controlled Cavity Length and Wide-Spectrum Lasing in FAMACsPb(BrI)3 Ternary Perovskite Vertical-Cavity Surface-Emitting Lasers with an All-Dielectric Dielectric Bragg Reflector

open access: yesCrystals, 2023
In this study, we utilized a dielectric Bragg reflector (DBR) as a mirror and positioned a wide-spectrum FAMACsPb(BrI)3 halide perovskite film between two DBRs to construct a vertical-cavity surface-emitting laser (VCSEL) structure.

InAlGaP vertical cavity surface emitting lasers (VCSELs): processing and performance [PDF]

open access: yesConference Proceedings. 1997 International Conference on Indium Phosphide and Related Materials, 2002
The performance of AlGaInP based visible VCSELs has been advanced with the application of new heterostructure designs and the technique of selective oxidation. Improved performance at elevated temperatures as well as high wallplug efficiency, low threshold devices have been demonstrated for devices operating in the 670-680 nm region.

Multimode VCSEL model for wide frequency-range RIN simulation [PDF]

open access: yes, 2008
In this paper, we present an equivalent circuit model for oxide-confined AlGaAs/GaAs VCSEL with the noise contribution adapted to optomicrowave links applications. This model is derived from the multimode rate equations.
