Gigahertz circular polarization oscillations in spin-polarized vertical-cavity surface-emitting lasers [PDF]

open access: yes, 2010
We analyze ultrafast circular polarization oscillations in a commercial vertical-cavity surface-emitting laser after spin injection at room temperature. The circular polarization exhibits faster dynamics than the intensity and longer persistence than the

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

Theoretical investigation of the dynamical and static characteristics of vertical-cavity surface-emitting lasers incorporating two-dimensional photonic crystals [PDF]

open access: yes, 2006
In this work we present a spatial and dynamical model of a semiconductor vertical-cavity surface-emitting laser (VCSEL) incorporating a spatial built-in optical waveguide created by the defect in a two-dimensional photonic crystal (PC). The PC is created

Operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser [PDF]

open access: yes, 2006
We report the operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser. The laser delivers 1 W at 855 nm and is pumped with a cost-effective fiber-coupled laser diode emitting at 806 nm.
