Book excerpt: Vertical cavity surface emitting lasers (VCSELs) have become of large commercial importance over the last two decades. They have become the dominant low cost, low power coherent sources in many applications such as optical sensing and short distance data communication. Despite their great success, there remain opportunities for improvement. Almost all commercially produced VCSELs are fabricated on structures based on a GaAs substrate. This restricts their wavelength range to between 650 and 1300 nm. Many potential applications exist at wavelengths outside of this range, so much work has gone into realizing VCSELs on other substrates. Though they have been realized, this has typically come with complexity that increases cost of producing such VCSELs. Of particular interest are InP-based VCSELs, which allow for emission at the wavelengths of 1320 nm and 1550 nm, two regions of high importance for optical communications applications. Another area of much research has been improving the modal characteristics of VCSELs. Typical VCSELs will lase in two polarization-degenerate optical modes. In addition, due to their structure, lateral optical modes also appear when a typical VCSEL's aperture becomes more than a few microns in size, limiting their output power. For high performance optical communications and sensing, a single mode laser is essential, so solving these mode problems is important. Next generation optical communication systems also require sources with an array of lasers of multiple output wavelengths or a tunable wavelength source that can be quickly tuned over a wide range of wavelengths. Schemes for both approaches have been implemented on VCSELs though various limitations of the current approaches have prevented them of being of large commercial importance to date. Tunable VCSELs have been limited in wavelength tuning speed by the thickness of their movable mirror. A commercially viable approach for an array of VCSELs of multiple wavelengths has also been difficult to achieve - most approaches shown to date require complex growth methods and the have not been able to achieve controllable wavelength spacing. High contrast gratings (HCGs) have emerged as an exciting new tool for achieving optical features such as broadband mirrors, planar lenses, and high quality factor resonators. Of particular use for VCSELs is a broadband mirror. These high contrast gratings in addition to acting as a mirror have features that can be exploited for many applications such as polarization differentiation and definable phase among others. HCGs are an exciting new tool for many optical applications. In this dissertation, we show how a high contrast grating can potentially solve several of the issues facing VCSELs and open new application spaces for VCSELs. First, we introduce the state of the art in VCSEL research and give a detailed overview of major areas of interest in VCSEL research. Next, we introduce high contrast gratings, discuss their implementation onto VCSELs, and demonstrate how they can be used to achieve more ideal modal qualities in the VCSEL, a single polarization mode as well as a larger area single transverse mode device. Then we show how the high contrast grating can be used in a tunable VCSEL to achieve ultra high speed tuning. Following that discussion, we shift our focus to implementing high performance, low cost VCSELs on InP with an HCG, showing two different approaches: a deposited Si HCG sitting on SiO2 and a monolithically-grown InP HCG. We conclude with a discussion of two approaches to achieve controllable arrays of VCSELs emitting at multiple wavelengths. The high contrast grating may be an important tool to achieving higher performance VCSELs, and VCSELs with features that enable new applications.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-01-25 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference book provides a fully integrated novel approach to the development of high-power, single-transverse mode, edge-emitting diode lasers by addressing the complementary topics of device engineering, reliability engineering and device diagnostics in the same book, and thus closes the gap in the current book literature. Diode laser fundamentals are discussed, followed by an elaborate discussion of problem-oriented design guidelines and techniques, and by a systematic treatment of the origins of laser degradation and a thorough exploration of the engineering means to enhance the optical strength of the laser. Stability criteria of critical laser characteristics and key laser robustness factors are discussed along with clear design considerations in the context of reliability engineering approaches and models, and typical programs for reliability tests and laser product qualifications. Novel, advanced diagnostic methods are reviewed to discuss, for the first time in detail in book literature, performance- and reliability-impacting factors such as temperature, stress and material instabilities. Further key features include: practical design guidelines that consider also reliability related effects, key laser robustness factors, basic laser fabrication and packaging issues; detailed discussion of diagnostic investigations of diode lasers, the fundamentals of the applied approaches and techniques, many of them pioneered by the author to be fit-for-purpose and novel in the application; systematic insight into laser degradation modes such as catastrophic optical damage, and a wide range of technologies to increase the optical strength of diode lasers; coverage of basic concepts and techniques of laser reliability engineering with details on a standard commercial high power laser reliability test program. Semiconductor Laser Engineering, Reliability and Diagnostics reflects the extensive expertise of the author in the diode laser field both as a top scientific researcher as well as a key developer of high-power highly reliable devices. With invaluable practical advice, this new reference book is suited to practising researchers in diode laser technologies, and to postgraduate engineering students.
