Method Of Making A Bidirectional Coupler For Communication Over Single Fiber
US Patent:
4961801, Oct 9, 1990
Filed:
May 9, 1984
Appl. No.:
6/608610
Inventors:
George A. Gasparian - Roanoke VA
Assignee:
Alcatel U.S.A. Corp. - New York NY
International Classification:
B32B 3122
US Classification:
156153
Abstract:
An assembly for bidirectional signal transmission over a single fiber is disclosed together with its method of manufacture. A hot coating of dichoric material is applied to a surface of a glass substrate. The substrate is processed into dichoric wafers having larger dimensions than the cross section of the fiber with which it is employed. The dichroic wafer is positioned over the end face of a polished fiber beamsplitter and secured thereto by a thin layer of optical grade epoxy. A second polished fiber beamsplitter may then be secured in a similar manner to the opposite side of the wafer. The coated wafer forms an acute angle of about 25. degree. with a plan perpendicular to the axis of each beamsplitter half. A bidirectional coupler is thereby formed.
Fiber Dichroic Coupler
US Patent:
4373775, Feb 15, 1983
Filed:
Jun 23, 1980
Appl. No.:
6/159972
Inventors:
George A. Gasparian - Roanoke VA
Assignee:
International Telephone and Telegraph Corporation - New York NY
International Classification:
G02B 5172
US Classification:
350 9615
Abstract:
An assembly for a bidirectional wavelength dependent beam splitter is disclosed together with a method of fabricating a thin film dichroic element. A dichroic material is applied to the surface of a suitable substrate. The substrate with this applied coating is then immersed in a solvent bath such that the dichroic thin film is either lifted off the substrate or the substrate is dissolved in the solvent bath, thus leaving an extremely thin film comprising the dichroic coating. The dichroic coating is positioned over the end face of a polished fiber beam splitter half and secured thereto by a thin layer of an optical grade epoxy. In the beam splitter configuration, a second polished fiber is secured in a similar manner to the opposite side of the thin film to form a beam splitter structure and hence, to provide a bidirectional wavelength dependent optical coupling device.
