A novel optical waveguide for integrated optics
IEEE Journal of Quantum Electronics, 1973A novel dielectric optical waveguide was made consisting of a guide pattern on a thin dielectric film. Almost all the power propagates in the thin film along the guide pattern. The existence of propagation modes of this waveguide was verified both theoretically and experimentally.

Optics and Optical Instruments
American Journal of Physics, 1961By B. K. Johnson New Tork: Dover Publications Inc. London: Constable & Co. Pp. viii + 224. Price $1.65. This book is an unaltered republication under a new title of the second (1947) edition of the author's Practical Optics. It is difficult to see why the title has been changed; this is a practical handbook which might appeal most to amateurs or to ...

Optical fibers for optical networking
Bell Labs Technical Journal, 2002This paper describes the influence of optical networking on the design of optical fibers. It reviews fundamental optical properties, describes the various fiber types, discusses the fiber requirements for optical networking, and considers the effects of fiber nonlinearities. Finally, the paper describes three new optical fibers from Lucent Technologies

Journal of Microscopy, 1987
SUMMARYImage analysis methods are first classified into four groups of theories related to optics, after which the associate hypotheses, the structures, the laboratory equipment and the mathematical framework for one of them, better known by the term of morphological optics, are studied in detail.

Patients with signs and symptoms consistent with acute monosymptomatic optic neuritis should undergo evaluation with gadolinium-enhanced MRI of the brain and orbits to determine whether or not they are at high risk for the development of clinically definite multiple sclerosis (CDMS).

Optic Nerves, Optic Chiasm, and Optic Tracts
1988The vertebrate optic nerves, optic chiasm, and optic tracts contain axons of retinal ganglion cells. These axons connect the retina, where light absorption produces patterned neuronal firing, to the brain, where these firing patterns can undergo further processing.

Physical Optics, Wave Optics, and Fourier Optics
1991When any of the dimensions or sizes of the components in an optical system is on the order of wavelength, then the methods discussed under geometrical optics do not give the proper solution to the problem. For this case, we must start from Maxwell’s equations, and derive the wave equation from which the proper solution to this problem can be obtained.

Linear optical characterization of nonlinear optical polymers for integrated optics
Macromolecular Chemistry and Physics, 1998Conjugated X (3) - active polythiophenes and polybenzobisthiazoles were characterized with respect to linear optical properties like refractive indices and linear absorption coefficients. The contributions of different alkyl side chains to optical properties are discussed for polythiophenes. The materials are discussed with respect to their ability as
