Book excerpt: Vertical Cavity Surface Emitting Lasers (VCSELs) offer many benefits over conventional edge-emitting lasers including economical microelectronic batch processing, easy extension to 2-D arrays, and of interest here, very large intrinsic bandwidths due to reduced cavity volume. Results of electrical characterization of a 19 GHz bandwidth 850 nm VCSEL are presented. Small-signal characterization and modeling of the frequency response and device impedance is presented. Large signal performance is studied using two-tone RF and high-speed digital measurements. Appropriate drive conditions for high-speed digital applications are demonstrated.

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.

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 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The motivation behind this work is to use derivative spectroscopy to better understand the inner workings of Vertical Cavity Surface Emitting Lasers (VCSELs) provided by Honeywell Inc. Derivative spectroscopy was used to investigate two types of Honeywell VCSELs, Oxide confined VCSELs and Proton bombarded VCSELs. To quantify the devices I-V (current-voltage) and P-I (power-current) electrical and optical measurements were used to show the devices have no major problems and that the measurements are reproducible. The I-V and P-I curves were taken to initially characterize devices. Having these curves supplies basic information such as laser threshold and data points for the slope of the operating regime. Using a voltage modulation technique derivative measurements dI/dV, d2IdV2, dL/dV were obtained and revealed subtle nonlinearities in the I-V and P-V data. Near field images of the optical output was correlated with the electrical measurements, and three mechanisms were identified that could be the cause of the derivative structure of the I-V curves.

Available in PDF, EPUB and Kindle. Book excerpt: In this study high-speed oxide-confined VCSELs were fabricated and characterized. Complete fabrication processes for top-emitting self- aligned and non-self-aligned 850nm and 980nm high-speed VCSELs were developed. A complete fabrication process for bottom-emitting, non-self-aligned, flip-chip bonded 980nm high-speed VCSELs was developed. Some of the critical fabrication steps that affect the VCSEL's speed were examined. The effect of a heat-sinking layer on the performance of high-speed VCSELs was demonstrated for 850nm and 980nm devices. To further improve the understanding of current high- speed VCSEL performance restrictions, the effect of external heating on the VCSEL's resonance frequency and damping factor was examined for top-emitting, self-aligned 980nm VCSELs. Furthermore, as the contacts of the self-aligned VCSELs go through annealing, etching, and oxidation, experiments on metal systems used were performed. To better model the high-speed devices, the dielectric properties of four different spin-on dielectrics were investigated.

This book was released on 2007-08-16 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertical-Cavity Surface-Emitting Lasers (VCSELs) have replaced edge-emitting laser diodes in several applications during the last years, e.g., in short distance optical data communication. Additionally, their invention has enabled new products such as optical computer mice using semiconductor lasers. However, VCSELs have intrinsically an unstable and not well-defined polarization, which has prohibited their usage in a considerable number of application areas up to now. Therefore, this thesis deals with polarization control of VCSELs. The highly sought-after polarization stabilization of VCSELs is achieved by using monolithically integrated surface gratings. The polarization control induced by these surface gratings has proven to be very reliable in thousands of grating VCSELs, under temperature variation, feedback, strain, and high-frequency modulation. Combining a surface grating with a surface relief, VCSELs having simultaneously a stable polarization and a high single-mode output power have been realized for the first time. Thus, surface grating VCSELs combine a well-defined polarization with low production costs and an excellent overall laser performance. With these properties, surface gratings outperform all other methods for polarization control of VCSELs tested before. Consequently, surface gratings have proven to be the method of choice for polarization control of VCSELs in commercial applications.
