On Laser Ranging Based on High-Speed/Energy Laser Diode Pulses and Single-Photon Detection Techniques
This paper discusses the construction principles and performance of a pulsed time-of-flight (TOF) laser radar based on high-speed (FWHM ~100 ps) and high-energy (~1 nJ) optical transmitter pulsesExpand

Polarization behavior of vertical-cavity surface-emitting lasers: Experiments, models and applications
Due to the emission of light perpendicular to the surface of the quantum well and the usually symmetric vertical resonator there is a priori no intrinsic polarization anisotropy mechanism in VCSELs.Expand

Optical-injection-induced polarization switching in polarization-bistable vertical-cavity surface-emitting lasers
We present a simple quasianalytical formalism for static polarization-resolved light-current characteristics of dual polarization mode vertical-cavity surface-emitting lasers (VCSELs) under opticalExpand

Polarization switching in VCSEL's due to thermal lensing
We demonstrate a new mechanism for polarization switching in slightly anisotropic vertical-cavity surface-emitting lasers (VCSEL's) based on index guiding due to the effect of thermal lensing. ThisExpand

Polarization stabilization in vertical-cavity surface-emitting lasers through asymmetric current injection
We present experimental evidence that asymmetric current injection in intracavity contacted vertical-cavity surface-emitting lasers (VCSELs) stabilizes the polarization of the emitted light.Expand
