Self-pulsing dynamics in a cavity soliton laser [PDF]

open access: yes, 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

Coherence in Multielement-Phased Vertical-Cavity Surface-Emitting Laser Arrays Using Resonance Tuning

open access: yesIEEE Photonics Journal, 2017
We show that optical coupling can be achieved reproducibly and with high yield by resonance tuning the elements of substrate-emitting and top-emitting vertical-cavity surface-emitting laser arrays.

Vertical Cavity Surface Emitting Lasers [PDF]

open access: yesMRS 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.
