Aza E. Mishkevich has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Deposition of highly doped silicon dioxide films
    Patent number: 6007685
    Abstract: The specification describes sputtering processes for the deposition of silicon dioxide films doped with high levels of oxides or other materials to alter the optical and/or electrical characteristics of the films. Sol gel methods are used to prepare composite sputtering targets of ultra fine mixtures of materials so the composition of the sputtered films replicate the composition of the target.

  • Dimensional control in the manufacture of optical fiber ferrule connectors by etching
    Patent number: 5897679
    Abstract: The specification describes techniques for chemically machining extruded glass preforms used to draw glass ferrules for optical fiber connectors. Using the chemical machining technique the dimensions of the preform, including OD, ID, and the OD to ID ratio can be adjusted so that the dimensions of drawn ferrules meet strict dimensional standards. The technique is especially useful for adjusting the dimensions of extruded preforms that have an inherent bow along in the length of the preform. The technique allows adjustment in dimensions while preserving a desired OD to ID ratio. Also described are techniques for reducing eccentricity and/or ellipticity of hollow bore glass preforms.
