First vertical-cavity surface-emitting laser made entirely in Poland [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2021 The paper presents the first vertical-cavity surface-emitting lasers (VCSELs) designed, grown, processed and evaluated entirely in Poland. The lasers emit at »850 nm, which is the most commonly used wavelength for short-reach (

Vertical Cavity With a Chirped Heterostructure Dual-Period High-Contrast Grating
IEEE Photonics Journal, 2022 A vertical cavity using a chirped heterostructure dual-period high-contrast grating (HCG) by simple fabrication is demonstrated. The reflectivity spectra of the vertical cavity were measured, consistent well with the calculated results.

Vertical Cavity Surface Emitting Terahertz Laser [PDF]
Physical Review Letters, 2012 Vertical cavity surface emitting terahertz lasers can be realized in conventional semiconductor microcavities with embedded quantum wells in the strong coupling regime. The cavity is to be pumped optically at half the frequency of the 2p exciton state.

Vertical Cavity Surface Emitting Lasers [PDF]
MRS Bulletin, 2002 The goal of this project was to increase the power of vertical cavity surface emitting lasers and to convert their wavelength into the blue/ultraviolet and the infrared for sensing applications. We have increased the power to the multi-watt level and have generated several milliwatts of blue light using optical pumping.

Reliability Analysis of Vertical Cavity Surface-Emitting Lasers Based on the Gamma Process
IEEE Access, 2020 Due to the long life and high reliability of vertical cavity surface-emitting lasers, the performance degradation experiment cost is high, and the experiment cycle is long, because the degradation failure process of a semiconductor laser is a monotonic ...

Spatial tomography of light resolved in time, spectrum, and polarisation
Nature Communications, 2022 The work harnesses principles of spatial state tomography to fully characterise an optical beam in space, time, spectrum, and polarisation. Analysis of the output of a vertical-cavity surface-emitting laser illustrates the technique’s capabilities.
