Numerical modeling of cylindrical semiconductor nano-lasers has been undertaken accommodating local gain variations in the active region of the device. Analysis is performed using both the cylindrical transfer matrix method and the finite element method.

A novel fibre-cavity design based on highly reflective gold coatings, vapor- deposited to the two end faces of a 400 um multimode waveguide, is presented. In contrast to common passive fibre-cavity approaches, the laser pulses are not coupled through the reflective coatings into the cavity but through a micro hole in one of the fibre end faces, which reduces the ...

  • Multipath Fading

    The overall performance of fixed point to point microwave systems is limited by short-duration, large, received signal power variations called fading. As a microwave signal travels over a relatively long path, the received signal may have propagated over several slightly different paths between the transmitter and the receiver. The different paths are caused by slight time and space- dependent variation in the atmospheric refractive index. This multipath fading is also called scintillation. The short echo usually varies in and out of phase with the direct signal fairly quickly. Its effect is to produce a short- duration, broad, frequency-independent signal power depression near the operating frequency. This produces the well-known flat fade. The overall received signal power loss due to the longer delayed signal echo of a dispersive fade is usually relatively insignificant. Both of these effects are illustrated in detail in this chapter.

It is fascinating reading for scie ntists, engineers, and graduate-level students in physics, chemistry, materials science, photonics, and electrical engineering.

  • Exotic Dielectrics Made of Periodic Structures

    Many extraction methods for approximately determining the electrical properties of a meta-material slab have been developed; however, they are subject to certain limitations. In this chapter, the phase and dispersion relations of a periodic medium will be taken into account for obtaining the effective refractive index of a medium with respect to an arbitrary incident condition.

  • Appendix A: Refractive Index of InGaAsP

    The phenomenal growth in Internet traffic has lead to a huge increase in demand for data transmission capacity on a worldwide level. As a result, wavelength division multiplexing (WDM) technology emerged, which makes it possible to transmit a large number of optical channels on a single optical fiber. An equally significant development occurred in optical networks, where switching and routing of signals takes place in the optical domain. This technology places special demands on the optical sources (lasers) used in the system. This text offers a description of the optical sources (equipment and devices) designed to meet these demands. Sources for DWDM Systems is intended for the engineers and graduate students working on optical networks. There is currently a nearly explosive interest in optical networks and the components required for such networks, but there is presently no single work which covers the variety of optical sources which may be used. This book will cover a particular component, tunable lasers, which is the next "big thing" in DWDM. The primary market are engineers developing tuneable lasers for optical networks, as well as graduate students enrolled in the optical engineering curriculum, especially: optical communication, semiconductor lasers, optical networks, and/or components for optical networks.
