Quantum cascade surface-emitting photonic crystal laser.
We combine photonic and electronic band structure engineering to create a surface-emitting quantum cascade microcavity laser. A high-index contrast two-dimensional photonic crystal is used to form a micro-resonator that simultaneously provides feedback for laser action and diffracts light vertically from the surface of the semiconductor surface. A top metallic contact allows electrical current ...
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 کاملMid-Infrared Surface-Emitting Two Dimensional Photonic Crystal Semiconductor Lasers
The mid-infrared (mid-IR) region, covering the electromagnetic spectrum from about 2.5 to 25 ┤m wavelength, is of unique interest for many applications, especially for molecular spectroscopy, because the vibrational frequencies of almost all target molecules and hydrocarbons are in this spectral region, such as NO, NO2, CO, CO2, HF, and CH4. The specific application areas for molecular spectros...
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 کاملGaN photonic-crystal surface-emitting laser at blue-violet wavelengths.
Shorter-wavelength surface-emitting laser sources are important for a variety of fields, including photonics, information processing, and biology. We report on the creation of a current-driven blue-violet photonic-crystal surface-emitting laser. We have developed a fabrication method, named "air holes retained over growth," in order to construct a two-dimensional gallium nitride (GaN)/air photo...
