This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the key advances in photonic technology in recent decades was the development of a new type of diode lasers emitting in the visible and infrared region. These vertical cavity surface-emitting lasers (VCSELs) emerged from a laboratory curiosity in 1977 [13] to an object of industrial mass production [14] and are currently used in many applications. The applications include communication, printing, and absorption spectroscopy [15]. Their rise in credibility has largely been motivated by the rapid evolution of their performance, the more sweeping recognition of their compatibility with low-cost wafer-scale fabrication, and their possible formation into specific arrays with no change in the fabrication procedure. Various applications such as advanced chemical sensors and high-density optical storage require coherent and small-size ultraviolet-emitting devices (below 400nm). Therefore, to extend the VCSEL emission to the ultraviolet (UV) region, intensive efforts have been made in the VCSEL technology. However, the achievement of such UV VCSEL is very challenging because of the various limitations and issues. The issues noticeably include the carrier injection, optical confinement, and highly reflective distributed Bragg reflectors (DBR) structures with a broad bandwidth operating in the UV region [16]. In this context, motivated by the reported large refractive index induced by boron incorporation [7], we propose to introduce the boron-based material systems (BAlGaN) as an innovative solution to address some of the encountered difficulties. The objective of the proposed research is to investigate and optimize new wide-bandgap BAlGaN material systems and illustrate their incorporation into the building blocks of vertical cavity surface-emitting laser structures for operation in the UV spectral range (

This book was released on 2003-09-04 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical, hands-on guidebook for the efficient modeling of VCSELs Vertical Cavity Surface Emitting Lasers (VCSELs) are a unique type of semiconductor laser whose optical output is vertically emitted from the surface as opposed to conventional edge-emitting semiconductor lasers. Complex in design and expensive to produce, VCSELs nevertheless represent an already widely used laser technology that promises to have even more significant applications in the future. Although the research has accelerated, there have been relatively few books written on this important topic. Analysis and Design of Vertical Cavity Surface Emitting Lasers seeks to encapsulate this growing body of knowledge into a single, comprehensive reference that will be of equal value for both professionals and academics in the field. The author, a recognized expert in the field of VCSELs, attempts to clarify often conflicting assumptions in order to help readers achieve the simplest and most efficient VCSEL models for any given problem. Highlights of the text include: * A clear and comprehensive theoretical treatment of VCSELs * Detailed derivations for understanding the operational principles of VCSELs * Mathematical models for the investigation of electrical, optical, and thermal properties of VCSELs * Case studies on the mathematical modeling of VCSELs and the implementation of simulation programs

This book was released on 1998 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research program is to develop novel techniques for the epitaxial growth and fabrication of vertical-cavity surface-emitting laser structures with lasing wavelengths in the 1.1-1.5 micron regime. Special emphasis will be on the realization of 1300 nm VCSELs and monolithic VCSEL arrays that are useful for the parallel optical data links that will interconnect future computer networks, whose nodes may be distributed across a wide range of distances and are interconnected by optical fibers. The 1300 nm VCSELs will provide improved fiber transmission performance as well as a more unified technology platform for the different levels of the interconnection heirarchy. One goal is to design and demonstrate a practical 1300 nm VCSEL structure that can be grown by a single epitaxial growth on a convention, high quality GaAs substrate. These structures will use InGaAsN quantum wells, as well as GaAs/AlAs distributed Bragg reflector (DBR) mirrors with a large index difference, which reduces the total thickness to a tractable level that makes a single-growth approach possible. In this program, we will develop an optimum device design for the fabrication of these VCSEL structures, and we will integrate them into monolithic arrays. We will evaluate the performance of the VCSELs in parallel optical links as well as in VCSEL-based optical switching networks.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Vertical-cavity surface-emitting lasers (VCSEL) are the most suitable light sources for certain optoelectronic applications because of their planner nature of light emission. VCSELs on GaAs substrates were grown by the molecular beam epitaxy technique. In this report we present detailed procedures to design and fabricate 850-nm top-emitting and 980-nm bottom-emitting VCSELs. First a test structure was grown by the molecular-beam epitaxy (MBE) technique and was characterized by reflectance and photoluminescence techniques. We used a wet oxidation process for current confinement in the laser structure. The VCSELs have low threshold current, low voltage drop and hence are suitable for hybridization onto silicon MOS circuits.
