16. Design, Fabrication, and Evaluation of High-Speed Vertical-Cavity Surface-Emitting Lasers
Abstract : The vertical-cavity surface-emitting laser (VCSEL) is a low cost light source with inherent high speed capabilities. These properties, along with low power consumption and a circular output beam, have made the VCSEL a well established component in digital communication networks, particularly in short reach optical data transmission where links consisting of GaAs-based 850nm VCSELs and multimode fiber have become the standard solution.

17. Developments for Improved Performance Vertical-Cavity Surface Emitting Lasers
Abstract : The vertical-cavity surface-emitting laser (VCSEL) is a type of laser diode that emits light from the surface of the chip from which it is manufactured rather than from a cleaved edge as so far has been common for most telecommunication lasers. VCSEL’s low cost, high power efficiency and low power consumption properties make it a very attractive signal source for many applications such as fiber optical communication, optical interconnects, 3D sensing, absorption spectroscopy, laser printing, etc. READ MORE

18. 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

19. Controlling the Optical Properties of Vertical-Cavity Surface-Emitting Lasers
Abstract : The insatiable demand for higher bandwidth in communication systems has led to the optical fiber trickling its way down to the consumer, gradually replacing the conventional copper cable. This trend is expected to continue, rendering these systems highly cost sensitive and therefore spurring the development of new breeds of semiconductor lasers, such as the vertical-cavity surface-emitting laser(VCSEL).
