Vertical cavity surface emitting terahertz laser.
Vertical cavity surface emitting terahertz lasers can be realized in conventional semiconductor microcavities with embedded quantum wells in the strong coupling regime. The cavity is to be pumped optically at half the frequency of the 2p exciton state. Once a threshold population of 2p excitons is achieved, a stimulated terahertz transition populates the lower exciton-polariton branch, and the ...
متن کاملVertical-cavity surface-emitting laser operating with photonic crystal seven-point defect structure
A vertical-cavity surface-emitting laser with a two-dimensional photonic crystal ~PC! structure has been investigated for single lateral mode operation. The PC confined mode can be controlled by the lattice constant, the hole diameter, the etching depth, and the defect structure. A seven-point defect structure is proposed to enhance the confinement effect, which is diluted by finite hole depth ...
متن کاملSingle fundamental mode photonic crystal vertical cavity surface emitting laser with 9 GHz bandwidth - Electronics Letters
Introduction: Stable single fundamental mode operation of a laser has drawn attention for a variety of applications in short and mid-range high quality optical networks, such as local area networks (LAN) and storage area networks (SAN). For these purposes, vertical cavity surface-emitting lasers (VCSELs) have been considered as promising optical sources over distributed feedback lasers not only...
متن کاملTwo-Dimensional Photonic Crystal Confined Vertical-Cavity Surface-Emitting Lasers
The two-dimensional photonic crystal (2-D PhC) structure has been investigated as a method for lateral mode control of vertical-cavity surface-emitting lasers (VCSELs). The 2-D PhC structures were designed using an equivalent index model developed for photonic crystal fibers combined with a plane wave expansion method. The etching depth dependence of the PhC structure was incorporated for the f...
متن کاملVertical Cavity Surface Emitting Lasers
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. Electrical pump has been less successful, but we have identified the proble...
