Single mode photonic crystal vertical cavity lasers
We report the accuracy of the photonic crystal model in describing the characteristics of vertical cavity surface-emitting lasers with lateral optical confinement consisting of a periodic array of etched circular holes. Experiments were carried out to compare predictions of the photonic crystal model to observed modal device characteristics, and the oxide aperture size was optimized to give max...
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...
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...
