    Author : Johan Gustavsson; Chalmers University of Technology; []
    Keywords : transverse modes; noise; modeling; Semiconductor laser; dynamics; vertical-cavity surface-emitting laser;

    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
