Spatial transverse modes and polarization states are experimentally studied in single vertical cavity surface emitting lasers (VCSELs) and phased-locked VCSEL arrays emitting at 1.3 mu m wavelength. Analysis of the polarization-resolved near fields, far fields and emission spectra permit the observation of the competition between the different modes ...

Vertical-cavity surface-emitting laser (VCSEL) sources for frequency domain photon migration
SPIE Proceedings, 2015Frequency domain photon migration (FDPM) uses modulated laser light to measure the bulk optical properties of turbid media and is increasingly being applied for noninvasive functional medical imaging. Though semiconductor edge emitting laser diodes (EELs) have been traditionally used for this application, we show that VCSELs exhibit performance ...

Highly Reliable 1060nm Vertical Cavity Surface Emitting Lasers (VCSELs) For Optical Interconnect
MRS Proceedings, 2012ABSTRACTHigh reliability, low power consumption and high speed laser diodes are required for optical interconnect. We developed 1060nm VCSELs with InGaAs/GaAs strained quantum wells, oxide-confined and double intra-cavity structures for that purpose.

Temperature Effects on the Power Characteristics of Vertical-Cavity Surface-Emitting Lasers (VCSELs)
2022A numerical analysis on temperature variation effects on the output power (Pout) characteristics of vertical-cavity surface-emitting lasers (VCSELs) is presented in this paper. While previous works in the literature mostly omitting the thermal effects.

SPIE Proceedings, 2009
Tunnel junctions have been widely used in the fabrication of Vertical Cavity Surface Emitting Lasers since it allows fabrication of low electrical resistance as well as low optical absorption Bragg mirrors. The basic idea is to inject holes through a highly doped reverse biased n+/p+ tunnel junction.

Laser Technology 2018: Progress and Applications of Lasers, 2018
A new structure of semiconductor lasers called the quantum-cascade vertical-cavity surface emitting laser (QC VCSEL) is proposed in the present paper. A structure of the QC VCSEL is a cross of the quantum-cascade laser (QCL) and the vertical-cavity surface-emitting laser (VCSEL).

Conference on Lasers and Electro-Optics Europe, 1996
The polarisation of the fundamental transverse mode of VCSEL can change when the injected current is altered. Switching of the polarisation associated to the excitation of higher order modes has been observed. It has also been noted that the strain induced during the fabrication causes birefringence in VCSEL.
