Available in PDF, EPUB and Kindle. Book excerpt: "Acoustooptic diffraction angles are expected to differ greatly from Bragg geometry when one uses optically anisotropic crystals and a rotation of the light polarisation takes place, since then the magnitudes of the two light wave vectors can be appreciably unequal. The only orientation that has been explicitly worked out prior to this thesis is that in which all the wave vectors are confined to the xy plane of uniaxial crystals. For this orientation, the two refractive indices involved are not direction dependent. In this thesis, the geometries for an interaction plane involving the optic axis in uniaxial crystals are calculated algebraically, first for an acoustic wave vector parallel and then perpendicular to the optic axis. In both cases one of the refractive indices is direction dependent. A computer program has also been written for numerically calculating the diffraction angles for all orientations and all directions of acoustic propagation in both uniaxial and biaxial crystals. A feature introduced in this program is that the crystal faces and their orientation with respect to other vectors is taken into account. Results obtained from the general, computer program agree with the results of all the three special cases and several geometries for biaxial crystals are presented."--

Available in PDF, EPUB and Kindle. Book excerpt: "A theoretical and experimental study on acoustic, optical and acoustooptic diffraction in anisotropic crystals is presented. It is shown that even though optical activity in quartz introduces only very small changes in the optical wave vector loci, its effects on acoustooptic diffraction geometry are nevertheless easily measurable. A calculation procedure for the diffraction angles incorporating optical activity is described and then experimentally verified. Topez, an optically biaxial crystal, is used to demonstrate the effects on shear-wave acoustooptic diffraction geometry of acoustic propagation along other thon symmetry axes and of interaction in nonsymmetry planes. The diffraction field of a plane aperture or a plane transducer in a highly anisotropic crystal is calculated by means of an angular spectrum of plane waves representation for which the phase velocity surface need only be defined numerically. This theory is experimentally verified by observing optical diffraction from a slit-type aperture in a biaxial crystal and by acoustooptic probe measurements of quasi-longitudinal and quasi-shear ultrasonic beam profiles under conditions of very high elastic anisotropy. Further verification is achieved by using published experimental measurements of ultrasonic surface wave beam profiles on lithium niobate. It is demonstrated that excellent agreement between theory and experiment is possible. Finally, the formalism and associated computational techniques are extended in order to examine various relevant problems in the diffraction and focusing of elastic surface waves."--

Book excerpt: New devices are described which are based on optical waveguides on lithium niobate crystals, using the material anisotropy, including couplers, electro-optic modulator and light multiplexer, and optical deflector and scanner using collinear acousto-optic interaction between surface acoustic waves and optical surface waves. Complete theory for the propagating modes and coupled modes is presented. A new type of waveguide is presented for use with surface acoustic wave devices for real-time direct scanning and Fourier transform scanning of optical images, which introduces no additional transmission loss over that for unguided propagation. Test pattern results demonstrate the ability of this type of waveguiding to increase the transverse resolution of such scanners, and good correlation between theoretical and experimental results is shown.

Available in PDF, EPUB and Kindle. Book excerpt: The paper discusses various aspects of diffraction and focusing for waves in anisotropic crystals, and the concepts are applicable to electromagnetic, ultrasonic bulk, or ultrasonic surface waves in homogeneous but arbitrarily anisotropic crystals. A numerical technique based on an angular spectrum of plane waves representation is shown to produce theoretical intensity profiles in good agreement with acoustooptic probe measurements of the diffraction field of a slit-type ultrasonic transducer launching quasi-longitudinal and quasi-shear waves in quartz along on axis of extreme anisotropy where the wave normal and the direction of energy flow are separated by angles greater than 20 degrees.

Available in PDF, EPUB and Kindle. Book excerpt: Optoelectronics is a rapidly expanding field of research and development. In years to come, it is destined to play a primary role in the growing information industry. The basic philosophy behind the science and technology of optoelectronics is to create and develop photonic devices in which optical photons (light waves) instead of electronic carriers, are manipulated for the conventional task performed by microelectronics. Thanks to the availability of large bandwidth at optical frequencies, the development of cost-effective low-loss low-dispersion silica fibers for optical transmission, and the possibility of ultra-fast two-dimensional processing, the field of present-day microelectronics is moving steadily towards this new technology of optoelectronics and photonics.This volume presents reviews of different areas of optoelectronics written by international experts in the field, covering most of the topics of recent importance. It includes detailed discussions on semiconductor lasers and optical amplifiers; optical fiber transmission; photodetectors; optoelectronic and photonic integrated circuits; light-wave telecommunications; optical signal and image processing; optical computing; nonlinear and integrated optics; space-time Fourier optics; optical metrology and sensing and optical interconnects. All chapters are written in the style of a textbook containing tutorial sections which should be of great use to graduate students. The volume should serve as an excellent book for graduate level course on optoelectronics, modern optical engineering, and optical communications.
