Energy-Efficient VCSELs for Optical Interconnects
Author: Philip Moser
Publisher: Springer
ISBN: 3319240676
Category : Science
Languages : en
Pages : 190
Book Description
This dissertation provides the first systematic analysis of the dynamic energy efficiency of vertical-cavity surface-emitting lasers (VCSELs) for optical interconnects, a key technology to address the pressing ecological and economic issues of the exponentially growing energy consumption in data centers. Energy-efficient data communication is one of the most important fields in “Green Photonics” enabling higher bit rates at significantly reduced energy consumption per bit. In this thesis the static and dynamic properties of GaAs-based oxide-confined VCSELs emitting at 850 nm and 980 nm are analyzed and general rules for achieving energy-efficient data transmission using VCSELs at any wavelength are derived. These rules are verified in data transmission experiments leading to record energy-efficient data transmission across a wide range of multimode optical fiber distances and at high temperatures up to 85°C. Important trade-offs between energy efficiency, temperature stability, modulation bandwidth, low current-density operation and other VCSEL properties are revealed and discussed.

Vertical-Cavity Surface-Emitting Lasers
Author: Julian Cheng
Publisher: CRC Press
ISBN: 9789056992637
Category : Technology & Engineering
Languages : en
Pages : 344
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 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.

Controlling the Emission Properties of High Power Semiconductor Lasers

ISBN: 9783832512934
Category :
Languages : en
Pages : 0
Book Description
The output powers of semiconductor lasers (SLs) are significantly enhanced by increasing the emitting area of the devices. However, increasing the output power can lead to deteriorated static and dynamic emission properties of high power SLs. In this thesis, various controlschemes based on spatially and spectrally filtered optical feedback are presented which, both, improve the beam quality and stabilize the nonlinear spatiotemporal emission dynamics of broad-area SLs and of broad-area vertical-cavity surface-emitting lasers (BA-VCSEL). Next to the dynamic emission properties of high-power SLs, their spatial coherence properties can be manipulated, which is of particular interest for various applications. A drastic reduction of the spatial coherence is shown to result in fundamentally modified beam characteristics of a BA-VCSEL. Time-resolved measurements of the evolution of the emission are presented giving insight into the thermal mechanisms responsible for the loss of spatial coherence.

Analysis and Design of Vertical Cavity Surface Emitting Lasers
Author: S. F. Yu
Publisher: John Wiley & Sons
ISBN: 9780471391241
Category : Science
Languages : en
Pages : 486
Book Description
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
