1. Long-Wavelength Vertical-Cavity Lasers : Materials and Device Analysis
Sammanfattning : Vertical-cavity lasers (VCLs) are of great interest as lightsources for fiber-optic communication systems. Such deviceshave a number of advantages over traditional in-plane laserdiodes, including low power consumption, efficient fibercoupling, on-chip testability, as well as potential low-costfabrication and packaging.

2. Processing technologies for long-wavelength vertical-cavity lasers
Sammanfattning : Vertical-cavity surface-emitting lasers (VCSELs) areattractive as potential inexpensive high-performance emittersfor fibre-optical communication systems. Their surface-normalemission together with the small dimensions are beneficial forlow-cost fabrication since it allows on-wafer testing,simplified packaging and effective fibre-coupling. LÄS MER
3. Modal Dynamics of Vertical-Cavity Surface-Emitting Lasers
Sammanfattning : 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).

5. High Speed Vertical Cavity Surface Emitting Lasers for Short Reach Communication
Sammanfattning : 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.
