The setting of a screw-operated tapered rod is used to control the separation between a spring-loaded beam element and a base element of a microtranslator with a positioning resolution of the order of 200 nanometers or less in a direction substantially parallel to a given single axis. A microtranslator assembly incorporating two such microtranslators oriented substantially perpendicular to one another is suitable for aligning a laser diode with a single-mode optical fiber to effect maximum coupling of light therebetween.

Microtranslator and microtranslator assembly

Miniaturized optics comprising transverse and lateral cylindrical lenses composed of millimeter-sized rods with diameters, indices-of-refraction and spacing such that substantially all the light emitted as an asymmetrical beam from the emitting junction of the laser is collected and translated to a symmetrical beam.

Enhanced optical coupling by phase evanescent fields is achieved by covering the planar layer of a waveguide with a thin metal oxide film incorporating a relief phase grating. The grating is originally formed in a metallic film covering the planar layer, which metallic film is converted to a metal oxide film by heating in an oxygen-containing atmosphere.

A species of fiber-optic thermometer, employing a gas-sealing movable reflecting element trapping a sealed gas column in a capillary as a temperature-sensitive medium, transfers a proportion of fiber-optic input light to a fiber-optic output as a single-valued function of temperature. This species provides a miniature thermometer exhibiting high temperature sensitivity.

Fiber-optic thermometer

A technique for generating long narrow microstructures based upon the shadowing effect of thick slits placed between a source and a substrate. The method is particularly well suited for forming optical waveguides using a mask having a slit with a width larger than the width of the stripe to be deposited and being thick relative to the width of said slit.

Process for forming an optical waveguide

The optical efficiency, with which a coupling portion of a fiber-optic can be coupled by evanescent fields to a planar optical waveguide through a phase-matching diffraction grating on the surface of the planar optical waveguide, is increased by deforming the coupling portion so that it is a negative replica of the undulating surface of the diffraction grating.
