چکیده

Title of Thesis: CHARACTERIZATION OF TWO-PHOTON ABSORPTION DETECTORS FOR APPLICATIONS IN HIGH-SPEED OPTICAL SYSTEMS Degree candidate: Reza Salem Degree and year: Master of Science, 2003 Thesis directed by: Professor Thomas E. Murphy Department of Electrical and Computer Engineering This thesis investigates the process of two-photon absorption in optical detectors. We begin by describing some concepts of nonlinear optics and considering two-photon absorption as a nonlinear effect. We next mention some applications of two-photon absorption in high-speed optical communication systems. We describe the complete experimental characterization of two-photon absorption in a silicon avalanche photodiode. Two-photon absorption sensitivity factors and polarization dependence are investigated both theoretically and experimentally. Finally we compare the results of the measurements with those obtained from a similar detector. CHARACTERIZATION OF TWO-PHOTON ABSORPTION DETECTORS FOR APPLICATIONS IN HIGH-SPEED OPTICAL SYSTEMS

The Role of Factors Influencing the Optical Properties of Yttrium Aluminum Garnet Ceramic Body

Yttrium Aluminum Garnet (Y3Al5O12) is a transparent ceramic with a wide range of applications such as high mechanical strength windows, high power laser sources and radiation detectors. The most important challenge in making these ceramics is the problem of low light transmittance, especially in the visible area in the range of 400 to 700 nm, which is greatly affected and reduced by various fac...

Ultraviolet detectors based on annealed zinc oxide thin films: epitaxial growth and physical characterizations

In this report, ultraviolet (UV) detectors were fabricated based on zinc oxide thin films. The epitaxial growth of zinc oxide thin films was carried out on bare glass substrate with preferred orientation to (002) plane of wurtzite structure through radio frequency sputtering technique. The structural properties indicated a dominant peak at 2θ=34.28º which was matched with JCPDS reference card N...

Comparison of ScintSim1 and Geant4 Monte Carlo simulation codes for optical photon transport in thick segmented scintillator arrays

  Introduction: Arrays of segmented scintillation crystals are useful in megavoltage x-ray imaging detectors for image-guided radiotherapy. Most previous theoretical studies on these detectors have modelled only ionizing-radiation transport. Scintillation light also affects detector performance. ScintSim1, our previously reported optical Monte Carlo code for such detector...

OPTICAL PROPERTIES OF CO-EVAPORATED THIN FILMS OF BINARY Bi 0-Te 0 AND Bi 0 -V 0 SYSTEMS

Thin films of binary Bi 0 -TeO and Bi 0 -V 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. The optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a PERKIN-ELMER uv/Vis spectrophotometer. It is found that the value of n=3/2 in the Davis-Mott equation is best fitted for the fundamental absorption edge f...

Nondegenerate Two- and Three-Photon Nonlinearities in Semiconductors

Two-photon absorption, 2PA, in semiconductors is enhanced by two orders of magnitude due to intermediate-state resonance enhancement, ISRE, for very nondegenerate (ND) photon energies. Associated with this enhancement in loss is enhancement of the nonlinear refractive index, n2. Even larger enhancement of three-photon absorption is calculated and observed. These large nonlinearities have implic...
