1. Modal Dynamics of Vertical-Cavity Surface-Emitting Lasers
Abstract : In this work, a comprehensive dynamic model has been developed for simulating a novel semiconductor laser type, referred to as the Vertical-Cavity Surface-Emitting Laser (VCSEL). The high-speed behavior was simulated and compared to experiments, where excellent agreement was found. READ MORE

4. High Speed Vertical Cavity Surface Emitting Lasers for Short Reach Communication
Abstract : The vertical cavity surface emitting laser (VCSEL) is a low cost light source with attractive performance characteristics such as low power consumption, high speed capabilities at low currents, and a circular output beam. These features have made the VCSEL an established component in digital communication networks, particularly in short reach optical data transmission applications where links consisting of GaAs-based 850nm VCSELs and multimode fiber have become the standard solution.

5. Optical Guiding and Feedback in Gallium Nitride Based Vertical Cavity Surface Emitting Lasers
Abstract : The gallium-nitride (GaN) semiconductor material has been the core of the revolutionary breakthroughs during the last two decades in the lighting industry, by enabling manufacturing of efficient blue light emitting diodes (LEDs), for which the 2014 Nobel prize in physics was awarded. The GaN technology has further led to violet edge-emitting lasers (EELs), enabling the Blu-ray disk technology, and also to the commercialization of directly green emitting EELs. READ MORE
