Significant reduction in inhomogeneous broadening of GaAs/AlGaAs V- groove quantum wires (QWRs) is achieved by growing them on vicinal (001) GaAs substrates misaligned by several degrees with respect to the [1 (1) over bar0] groove direction. Low temperatu ...

Applications of long-wavelength (lambda > 1 mu m) vertical-cavity surface-emitting lasers (VCSELs) generally require close control over wavelength and polarization of the emitted light. In most cases, single mode and polarization stable lasing is desired. ...

High spontaneous-emission coupling and low-threshold lasing is achieved in semiconductor photonic-crystal cavities using short quantum wires. Lasing is established and characterized based on the linewidth narrowing and time-resolved photon dynamics. (C)2009 Optical Society of America

Low-threshold lasing is experimentally achieved for the first time in semiconductor photonic-crystal nanocavities embedding site-controlled quantum wires. The effect is established via direct observation of the stimulated emission in the time domain.

Record-high fundamental mode output power of 1.5 mW at 100 degrees C is achieved with InAlGaAs-InP/AlGaAs-GaAs 1550 nm wavelength vertical cavity surface emitting lasers (VCSELs) produced by a modified wafer fusion technique. A broad wavelength setting on ...

We report on the design, fabrication and characterization of electrically pumped vertical external cavity surface emitting lasers (EP-VECSELs) emitting at 1470 nm. We demonstrate 6.2 mW of CW output power, which represents the highest power value reported ...

Polarization stable, wafer-fused 1310 nm VCSELs employing sub-wavelength shallow gratings on their top DBR and emitting 1.5 mW single mode output power in the 20 degrees C - 75 degrees C temperature range are demonstrated. (C) 2008 Optical Society of America

Optical injection locking of 1.3-mu m phase-locked VCSEL arrays defined by patterned tunnel junctions and wafer fusion is investigated experimentally and theoretically. The impact of the overlap between the master laser injection beam and the injected mode ...

Spatial transverse modes and polarization states are experimentally studied in single vertical cavity surface emitting lasers (VCSELs) and phased-locked VCSEL arrays emitting at 1.3 mu m wavelength. Analysis of the polarization-resolved near fields, far fi ...
