Nanosecond Pulse Generation in Optically Pumped Dual-Wavelength Vertical-External-Cavity Surface-Emitting Laser

IEEE Photonics Journal, 2022
In this study, nanosecond-pulse lasing was achieved using a vertical-external-cavity surface-emitting laser (VECSEL) with only a single gain chip. A simple linear-cavity setup was used for the VECSEL, and pulsed lasing with a pulse width of ∼9 ns ...

Timing Jitter Characterization of a Free-Running SESAM Mode-locked VECSEL

IEEE Photonics Journal, 2011
We present timing jitter measurements of an InGaAs quantum well vertical external cavity surface emitting laser (VECSEL) passively mode locked with a quantum dot semiconductor saturable absorber mirror (SESAM) at 2-GHz repetition rate. It generates 53-mW

Self-pulsing dynamics in a cavity soliton laser

, 2010
The dynamics of a broad-area vertical-cavity surface-emitting laser (VCSEL) with frequency-selective feedback supporting bistable spatial solitons is analyzed experimentally and theoretically. The transient dynamics of a switch-on of a soliton induced by

External cavity mode structure of a two-mode VCSEL subject to optical feedback

, 2007
We consider a multi-transverse-mode vertical-cavity surface-emitting laser (VCSEL) subject to optical feedback. The system is modeled by a partial differential equation for the spatial carrier population, which is coupled to delay differential equations ...

Optimization of an avionic VCSEL-based optical link through large signal characterization [PDF]

, 2008
Optical communication systems have been widely preferred for network communications, especially for Datacoms Local Area Network links. The optical technology is an excellent candidate for on-board systems due to the potential weight saving and EMC ...

Development of high-speed directly-modulated DFB and DBR lasers with surface gratings [PDF]

, 2011
The conventional distributed feedback and distributed Bragg reflector edge-emitting lasers employ buried gratings, which require two or more epitaxial growth steps.

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

Bifurcation analysis of a multi-transverse-mode VCSEL

, 2008
We study the behaviour of a multi-transverse-mode vertical-cavity surface-emitting laser subject to optical feedback in which the optical modes are coupled through the external round-trip. Starting from a delayed partial differential equation description
