Low Noise, High Detectivity Photodetectors based on.
LED-based photodetector. Therefore, by integrating LED-based photodetectors as either transmitter or receiver, optical wireless communication could be easily implemented for bidirectional visible light communication networks at low-cost. Therefore, this dissertation focus on the investigation of the photodetection characteristics of InGaN.
This dissertation will develop Si-based GeSn photodetectors technology to realize low-cost high-performance focal plane arrays detectors working in the SWIR towards MIR. It began with the development of fabrication process of single element GeSn photoconductor and photodiode, followed by systematic characterization and analysis of detectors.
Travelling-Wave Photodetectors by Kirk Steven Giboney A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Electrical and Computer Engineering Committee in Charge Professor John E. Bowers, Co-Chairperson Professor Mark J. W. Rodwell, Co-Chairperson Professor Larry A. Coldren Professor.
A photodetector is an optoelectronic device that absorbs optical energy and converts it to electrical energy, which usually manifests as a photocurrent. Photodetectors are widely used in optical communication systems. In this application, detectors receive the transmitted optical pulses and convert them, with as little loss as possible, into electronic pulses that can be used by a telephone, a.
Chapter 5 Photodetectors and Solar Cells 3.1 Photodetectors Photodetectors come in two basic flavors: i) Photoconductors ii) Photovoltaics A photoconductor is a device whose resistance (or conductivity) changes in the presence of light. A photovoltaic device produces a current or a voltage at its output in the presence of light. In this Chapter.

Semiconductor Photodetectors 1.1. Brief overview of semiconductor materials A semiconductor material is a continuous crystalline medium characterized by an energy band structure corresponding, in the case of an infinite crystal, to a continuum of states (which, in practice, means that the characteristic dimensions of the crystal are.
In addition to high-power radiation sources, compact, low-cost, and high-sensitivity THz photodetectors are also essential components towards realization of THz sensing and spectroscopy systems. This thesis also proposes a novel type of sensitive THz photodetector, the quantum-cascade detector (QCD), which operates at non-zero electrical bias.
