Book Description
Since first coming into existence in the early 90s, the vertical-cavity surface-emitting laser (VCSEL) has made several quantum leaps in performance. The performance of VCSELs now exceeds that of edge-emitting lasers in many respects, and offers a superior optical beam and much easier monolithic integrability. As the VCSEL technology improves furth

Book Description
Vertical External Cavity Surface Emitting Lasers Provides comprehensive coverage of the advancement of vertical-external-cavity surface-emitting lasers Vertical-external-cavity surface-emitting lasers (VECSELs) emit coherent light from the infrared to the visible spectral range with high power output. Recent years have seen new device developments – such as the mode-locked integrated (MIXSEL) and the membrane external-cavity surface emitting laser (MECSEL) – expand the application of VECSELs to include laser cooling, spectroscopy, telecommunications, biophotonics, and laser-based displays and projectors. In Vertical External Cavity Surface Emitting Lasers: VECSEL Technology and Applications, leading international research groups provide a comprehensive, fully up-to-date account of all fundamental and technological aspects of vertical external cavity surface emitting lasers. This unique book reviews the physics and technology of optically-pumped disk lasers and discusses the latest developments of VECSEL devices in different wavelength ranges. Topics include OP-VECSEL physics, continuous wave (CW) lasers, frequency doubling, carrier dynamics in SESAMs, and characterization of nonlinear lensing in VECSEL gain samples. This authoritative volume: Summarizes new concepts of DBR-free and MECSEL lasers for the first time Covers the mode-locking concept and its application Provides an overview of the emerging concept of self-mode locking Describes the development of next-generation OPS laser products Vertical External Cavity Surface Emitting Lasers: VECSEL Technology and Applications is an invaluable resource for laser specialists, semiconductor physicists, optical industry professionals, spectroscopists, telecommunications engineers and industrial physicists.

Book Description
Despite the burst of the telecommunication market bubble, demands for bandwidth still seem to be growing as new applications are introduced. Optical fiber networks are capable of meeting such demand and long-wavelength vertical-cavity surface-emitting lasers (VCSELs) are attractive candidate for low cost light sources. Extensive researches resulted in dramatic improvements of the device performances with the number of different approaches such as wafer fusion, metamorphic, buried-tunnel-junction (BTJ), and all epitaxial approaches. Among them, all epitaxial VCSEL where all the components of device are grown in single growth is especially attractive for low cost application. Both DBR and the active region can be grown with AlInGaAs on InP substrate--this material system has been well developed over a couple of decade and can offer stable growth. However AlInGaAs DBR suffers from the fact that the maximum achievable reflectivity is lower than other DBRs. This can be compensated by using bipolar cascaded (BC) active region which provides higher gain. Moreover significantly higher differential quantum efficiency is achievable. The goal of this thesis was to investigate and develop practical 1.55 mu m VCSEL with cascaded active region. The scalability of BC VCSEL was investigated both theoretically and experimentally. The current confining aperture was developed using ion implantation. While continuous wave operation was not realized, the device with greater than 120% differential efficiency was demonstrated.

Book Description
Since the development of low loss optical fibers over 25 years ago, optical communications has become the system of choice for worldwide communication networks. Some of the many advantages over previous systems include: large transmission bandwidth, immunity to electromagnetic interference, low transmission loss, low weight, low power consumption, and relatively low cost. As multimedia services including the internet, cable television, high definition television (HDTV), and computer links become indispensable in our daily lives, large amounts of data must be transmitted through the information highway. This poses a serious challenge on the current communication network.
