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: Selectively oxidized vertical cavity lasers emitting near 1300 nm using InGaAsN quantum wells are reported for the first time which operate continuous wave below, at and above room temperature. The lasers employ two n-type Al.sub.0.94 Ga.sub.0.06 As/GaAs distributed Bragg reflectors each with a selectively oxidized current aperture adjacent to the active region, and the top output mirror contains a tunnel junction to inject holes into the active region. Continuous wave single mode lasing is observed up to 55.degree. C.

Available in PDF, EPUB and Kindle. Book excerpt: Vertical Cavity Surface Emitting Laser (VCSEL)-based data links are attractive due to their low-power dissipation and low-cost manufacturability. This chapter reviews the foundations for this technology, as well as the device and module design challenges of extending the data rate beyond the current level. We begin with a review of data communications from the business perspective, and continue with a brief discussion of the current and future standards. This is followed by a survey of recent advances in VCSELs, including data links operating at 28Gb/s. We review the recent efforts on ultra-fast data links and discuss the advantages of the different approaches. We also examine key design aspects of optical transceiver modules and we focus our discussion on novel applications in high-performance computing using both multi-mode and single-mode fiber optics. We highlight the importance of the device/component-level and system-level modeling and show some modeling examples with comparison to measured data. We conclude with a comparison of the VCSEL-based data links with other competing technologies, including silicon photonics and short-cavity edge emitting lasers.

Download or read book GaAs based 1550 Nm GaInNAsSb Lasers written by Tomás Sarmiento Suarez and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-cost, long-wavelength light sources are indispensable for the widespread deployment of fiber-to-the-home networks. Vertical cavity surface emitting lasers (VCSELs) are ideal for these applications due to their high fiber-coupling efficiency, low power consumption, simple packaging and wafer-scale manufacturability. In particular, VCSELs emitting in the C-band (1530-1565 nm) are highly desirable given that the fiber optical loss is minimal in this wavelength range. High-performance 1550 nm InP-based VCSELs using various distributed Bragg reflector (DBR) technologies have been demonstrated, but these approaches generally require complex and extensive processing, leading to high manufacturing costs. In contrast, GaAs-based VCSELs can be processed in a simple and robust way by exploiting the superior material properties of Al(Ga)As/GaAs DBRs and the oxidation of AlAs layers for electrical and optical confinement. Dilute nitride GaInNAsSb alloys emitting in the 1200-1600 nm wavelength range can be grown coherently on GaAs substrates, enabling the realization of long wavelength GaAs-based lasers. Despite significant challenges in the growth of such highly-mismatched alloys, 1550 nm GaInNAsSb lasers with relatively low threshold current densities have been demonstrated. This dissertation describes recent progress on the development of GaInNAsSb lasers. Optimization of the growth and annealing conditions enabled a four-fold enhancement of the luminescence efficiency of GaInNAsSb quantum wells with GaNAs barriers. In addition, incorporation of GaAsP barriers significantly improved the temperature stability of the lasers. The improved quantum wells enabled the realization of the first electrically-pumped GaInNAsSb VCSELs emitting in the C-band that operate at and above room temperature.
