Microchip vertical external cavity surface-emitting lasers

The 16th Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2003. LEOS 2003., 2003
In this paper we have demonstrated monolithic "microchip" vertical external-cavity surface-emitting lasers (VECSEL), in which a cavity is formed between the VECSEL semiconductor back mirror and a dielectric mirror coating on the outer surface of the heat spreader, and where pump-induced thermal lensing may provide cavity stability. We have demonstrated

Cavity solitons in vertical-cavity surface-emitting lasers [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014
We investigate a control of the motion of localized structures (LSs) of light by means of delay feedback in the transverse section of a broad area nonlinear optical system. The delayed feedback is found to induce a spontaneous motion of a solitary LS that is stationary and stable in the absence of feedback.

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 ...

Multimode vertical-cavity surface-emitting lasers under spin injection [PDF]

APL Photonics
Recent research revealed that single-mode vertical-cavity surface-emitting lasers under spin injection (spin-VCSELs) have the potential to revolutionize laser technology for short-haul optical communications. While previous studies have focused solely on
