Vertical-Cavity Surface-Emitting Laser (VCSEL)

Proceedings of the IEEE, 2013
The vertical-cavity surface-emitting laser (VCSEL) is becoming a key device in high-speed optical local area networks (LANs) and even wide-area networks (WANs). This device is also enabling ultraparallel data transfer in equipment and computer systems, including storage area networks (SANs) and wide optoelectronics fields. In this paper, we will review

Polarization modes in long-wavelength vertical-cavity surface-emitting lasers (VCSELs) and VCSEL-arrays

Proceedings of SPIE, 2010
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 ...

Quantum-Cascade Vertical-Cavity Surface-Emitting Laser (QC-VCSEL)

2018 20th International Conference on Transparent Optical Networks (ICTON), 2018
The paper is devoted to physics of an operation of new semiconductor lasers, namely – the quantum-cascade vertical-cavity surface-emitting diode lasers (QC-VCSELs). These lasers are expected to exhibit advantages of both the vertical-cavity surface-emitting diode lasers (VCSELs) and the unipolar quantum-cascade lasers (QCLs).

Nonlinear spectroscopy with a vertical-cavity surface-emitting laser (VCSEL)

Applied Physics B: Lasers and Optics, 2000
We have evaluated the suitability of a vertical-cavity surface-emitting laser diode (VCSEL) for spectroscopic applications. Despite its low output power it is possible to observe narrow resonances in a saturated absorption spectroscopy experiment on the cesium D 2 transition at 852 nm, limited in width by the laser linewidth of several tens of MHz ...

Design and modeling of a vertical-cavity surface-emitting laser (VCSEL)

2008 IEEE International Conference on Semiconductor Electronics, 2008
In this paper, we attempt to design, simulate and characterize an InGaAs-based vertical-cavity surface-emitting laser (VCSEL) employing InGaAsP multi-quantum wells sandwiched between GaAs/AlGaAs and GaAs/AlAs distributed Bragg reflectors using an industrial-based numerical simulator.

Modes Distribution in Quantum-Cascade Vertical-Cavity Surface-Emitting Laser (VCSEL)

2018 20th International Conference on Transparent Optical Networks (ICTON), 2018
Performance of any semiconductor laser depends on an efficiency of mutual interaction between electrical carriers and an optical field. It concerns, in particular, performance of considered here new semiconductor lasers – the quantum-cascade vertical-cavity surface-emitting diode lasers (QC VCSELs). These lasers are anticipated to exhibit advantages of

Vertical cavity surface emitting lasers (VCSELs) and VCSEL arrays for communication and sensing

2022
Future generations of optical wireless communication and sensing systems require compact, low-cost, reliable, and highly efficient light sources capable of transmitting modulated beams across free space at gigabit per second (Gbps) data rates and pulsed beams with sub-nanosecond rise and fall times.
