This book was released on 2005 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.
