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

, 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

Spectral behavior of long wavelength VCSELs [PDF]

, 2008
For a long time, only a small wavelength range of Vertical-Cavity Surface-Emitting Lasers (VCSEL) was available. The current evolution in process technology allows the fabrication of long wavelength VCSEL that is interesting for Telecom systems because ...

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

, 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.

Mode structure of a vertical-cavity surface-emitting laser subject to optical feedback

, 2006
We present an analysis of the external cavity mode (ECM) structure of a vertical-cavity surface-emitting laser subject to optical feedback. We consider a model in which two transverse optical modes are excited.

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

, 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

Optical tuning of vertical-cavity surface-emitting laser side-pumped neodymium-doped yttrium aluminum garnet laser cavity

High Power Laser Science and Engineering
High-power 808 nm vertical-cavity surface-emitting laser (VCSEL) chips have unique characteristics for neodymium-doped yttrium aluminum garnet (Nd:YAG) laser pumping compared with conventional edge-emitting laser bars, including a chip surface with high ...
