    The tunneling phenomenon known as frustrated total internal reflection is described in classic texts and research papers, but students are generally not exposed to the concept in standard optics or electromagnetics courses. It is shown that the tunnel effect may serve as the basis of a nonresonant lossless optical filter. The resolution capabilities of this filter are rather limited, and the best ...

    The design of an optical transmitter/receiver system, suitable as an educational project for the demonstration of low-noise wireless voice communication in the laboratory, is described. The system, having a range in excess of 8 m, uses a VCO (voltage-controlled oscillator), operating at the center frequency of 100 kHz, to achieve voice data encoding. Optical decoding at the receiver is performed u... View full abstract»

    The use of an off-axis holograpic optical element (HOE) as a powerful spectrograph to observe the buildup of laser oscillation as excitation is increased through the threshold value is described. The spectrum in the focal plane may be sensed by a charge-coupled device with output displayed on an oscilloscope screen. The lessons that can be learned from this experiment are discussed View full abstract»

  • Transient electromagnetic plane wave reflection from a dielectric slab

    Publication Year: 1992, Page(s):170 - 175
    Cited by:  Papers (3)

    Reflection of a transient plane wave normally incident upon a lossless dielectric slab is analyzed via the Fourier transform. The exact expression for the time-harmonic field is used in the inverse Fourier transform to obtain the transient response to a class of exponential exciting functions. Cauchy's integral theorem and the Poisson sum formula yield closed-form expressions for the unit step and... View full abstract»

    A simple electrical network is used to represent the five differential equations describing basic phenomena in one-dimensional semiconductor devices. Both standard and integrated approaches for solving transport equations are developed. Also, an electrical network equivalent for the nonlinear Poisson equation was derived. It allows students to better understand the physical phenomena and the proce... View full abstract»

    It is shown that a surprising number of traditional topics, such as the Rayleigh resolution criterion, spatial filtering, bandlimited signals, the sampling theorem, phase contrast microscopy, and white light holography, can be explained using simple interference theory. These basic results are then easily extended to the N-source case to introduce diffraction theory, and facilitate the te... View full abstract»
