Download or read book Vertical Cavity Surface Emitting Lasers written by Julian Cheng and published by CRC Press. This book was released on 2000-07-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 further, and their number and variety multiply, their potential applications will likely expand at a rapid pace. Vertical-cavity Surface-Emitting Lasers: Technology and Applications addresses two main objectives. It provides the researcher and device engineer with a reference guide to understanding the physical principles as well as the practical design concepts of VCSELs. Furthermore, it provides the system designer or application engineer with a review of the properties of VCSELs, and an overview of some of the applications in which the VCSEL has already played an important role. This book features contributions from prominent researchers in the field.

Available in PDF, EPUB and Kindle. Book excerpt: As coaxial cable networks rapidly approach their data carrying limit an alternative method of data solution to this problem is needed to cope with the demand for high data rates. A low cost solution to this problem is to transmit data in parallel via cheap multimode plastic fibre ribbons and to use monolithic arrays of red VCSELs as the optical transmitters. VCSELs' intrinsic high speed, planar geometry and circular beam profile make them ideally suited for such systems. Other commercial applications include bar code readers, laser printing, visible displays (such as head up displays) and the automotive and aerospace industry. Visible VCSELs suffer from excess heating due to several factors. In particular the top p-doped A1GaAs distributed Bragg reflector (DBR) mirror presents a high series resistance due to the large valance band offset leading to strong Ohmic heating and poor thermal impedance. This situation is amplified by the stipulation that the VCSEL is bonded down with the p-doped mirror uppermost, which further increases the thermal impedance of the packaged laser.To overcome these problems this work considers methods of extracting the heat generated internally by examining different fabrication schemes. By means of a thermal model developed, the optimum fabrication parameters with regard to mesa diameter and substrate thickness that provide the most efficient heat extraction from the devices are determined. The use of substrate etch back and wafer-bonding techniques will allow the VCSEL to be processed on alternative substrates such as Si which will improve the device heat sinking due to silicon's good thermal conductivity. In addition, the ability to fabricate VCSELs on Si increases the feasibility of integration with Si CMOS electronics.This work has produced devices emitting at 668 nm (20°C) with record heat sink temperature operation up to 80°C and over 1 mW single mode output power at 20°C. Devices emitting at 665 nm and 675 nm have been fabricated, producing multimode output powers at 20°C of 2 mW and 2.8 mW respectively. Bondable VCSELs have been successfully transferred to non GaAs substrates with no deterioration of performance. A six-element array operating at 675 nm capable of being butt coupled to 125 ~m diameter fibre has produced over 12 mW output power at 20°C with no evidence of thermal cross talk between elements in the array.

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

Book excerpt: (Al{sub y}Ga{sub 1-y}){sup 1-x}In(subscript x)P semiconductor alloys lattice-matched to GaAs are widely used in visible optoelectronic devices. One of the most recent developments in this area is the AlGaInP-based red vertical cavity surface emitting laser (VCSEL). These lasers, which employ AlGaInP active regions and AlGaAs distributed Bragg reflectors (DBRs), have demonstrated continuous-wave (CW) lasing over the 630--690 nm region of the spectrum. Applications for these lasers include plastic fiber data communications, laser printing and bar code scanning. In this paper, the authors present an overview of recent developments in the processing and performance of AlGaInP based VCSELs. This overview will include a review of the general heterostructure designs that have been employed, as well as the performance of lasers fabricated by both ion implantation and selective oxidation.
