Abstract:
An optical branch and switch based on a unique mirror effect were fabricated by varying the amount of Ti diffused in a LiNbO(3) waveguide, and their properties were investigated. In this type of optical branch, the branching ratio of the light intensity could be varied by the electric field as well as by the separating angle and the effective indices of the waveguides. The main features of this optical switch are (1) small and simple electrode form and (2) a separating angle large enough to accommodate a number of switches on a single substrate. The ratio of the optical branch light intensity to that of the main waveguide was varied from 0.10 to 12.4 by applying the electric field from 0 V/microm to 8 V/microm.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
