Annealing effects of 850 nm vertical-cavity surface-emitting lasers after proton irradiation

Heliyon, 2022
A long-term annealing experiment was performed using 850 nm vertical-cavity surface-emitting lasers (VCSELs) irradiated with 10 MeV protons. Static parameters such as the threshold current, slope efficiency, and light output power were tested using ...

Relative intensity noise of temperature-stable, energy-efficient 980 nm VCSELs

AIP Advances, 2017
The relative intensity noise (RIN) of temperature-stable, energy-efficient oxide confined vertical-cavity surface-emitting lasers (VCSELs) have been investigated. Low energy consumption data transmission is achieved by using small oxide-aperture diameter

Spin induced gigahertz polarization oscillations in vertical-cavity surface-emitting laser devices [PDF]

, 2011
Spin-controlled vertical-cavity surface-emitting lasers (VCSELs) have been intensively studied in recent years because of the low threshold feasibility and the nonlinearity above threshold, which make spin-VCSELs very promising for spintronic devices ...

High-Efficiency Quantum Dot Lasers as Comb Sources for DWDM Applications

Applied Sciences, 2022
The trend of data center transceivers is to increase bandwidth while simultaneously decreasing their size, power consumption, and cost. While data center links have previously relied on vertical-cavity surface-emitting lasers (VCSELs) or in-plane lasers ...

Spectral behavior of long wavelength VCSELs [PDF]

, 2008
For a long time, only a small wavelength range of Vertical-Cavity Surface-Emitting Lasers (VCSEL) was available. The current evolution in process technology allows the fabrication of long wavelength VCSEL that is interesting for Telecom systems because ...

High-speed modulation, wavelength, and mode control in vertical-cavity surface-emitting lasers

, 2022
Paper 93810F, 10 S.We address demands and challenges for GaAs-based Vertical-Cavity Surface-Emitting Lasers (VCSEL) in data communication. High speed modulation (similar to 50Gb/s) at a high reliability can be realized with a proper VCSEL design ...
