Abstract: Methods and apparatus for the removal of foreign matter, such as oil and dust, from the end faces of optical fiber and optical fiber connectors. Cleaning is effected by bringing carbon nanotube material into contact with an end face to create a differential adhesion in the proximity of the end face that more strongly attracts foreign matter residing on the end face to the carbon nanotube material than its attraction to the end face. The carbon nanotube material is applied with cleaning swabs or tapes that are used to clean end faces with swiping actions.

Abstract: A non-kink, non-hockling optical cable comprising an optical fiber capable of propagating light along its longitudinal axis. A buffer layer made of a soft plastic material surrounds the silica core and cladding, and a supplemental layer surrounds the buffer layer. The supplemental layer consists essentially of a liquid crystal polymer (LCP) material to enhance the tensile strength of the optical fiber. Finally, an encasing polymer layer with a breaking strain greater than 30%, surrounds the supplemental layer, to increase the flexibility of the optical cable.

The housing has at least one section of wall comprising a layer of liquid crystal polymer (LCP). At least one hermetically sealed electrical port is formed in the LCP wall section over a predetermined area and comprises a layer of metal adhered to and overlying the predetermined area on the of the LCP wall section. An electrode passes through the metal from the exterior of the system to the interior space to provide an electrical communication path between the optoelectronic components and the exterior of said packaging system.

Abstract: An electro-optic electromagnetic field sensor system includes an electro-optic sensor located at an electromagnetic field sensing site for detecting an intensity of an electromagnetic field. The sensor changes an optical measuring signal received from a laser source to an optical sensor signal representative of the electromagnetic field intensity. An optical bias adjust unit optically coupled to the laser source adjusts the bias operating point of the electro-optic sensor responsive to an electrical bias adjust signal which includes a test signal component. A detector optically coupled to the electro-optic sensor converts the optical sensor signal to an electrical sensor signal and detects a feedback signal indicative of the transfer function of the electro-optic sensor operating on the test signal component. A bias control circuit electrically coupled to the optical bias adjust unit generates the bias adjust signal responsive to the feedback signal. An optical input fiber couples the optical measuring signal from the laser source to the electro-optic sensor and an optical output fiber couples the optical sensor signal to the detector.

Abstract: A method for diffusing titanium into a single-crystal lithium niobate substrate and guided wave devices produced therefrom provide improved mode match with coupled fibers. Preferably, the titanium diffusion occurs at a diffusion temperature for a time between about 8 hours and about 18 hours. Outdiffusion of lithium oxide is allowed to occur during titanium diffusion. The outdiffused region, typically at least about 25 .mu.m, is much deeper than the titanium diffusion depth, typically about 5-10 .mu.m.

Abstract: A method for co-diffusing titanium and aluminum into a single-crystal lithium niobate substrate and guided wave devices produced therefrom are provided. Titanium diffused into the substrate forms a light guiding region. A layer of aluminum deposited over the light guiding region and diffused into the substrate buries the light guiding region below the substrate surface. In an alternate embodiment, a layer of aluminum forms a mode shaping region which surrounds the light guiding region on two sides. The mode shaping region has ordinary and extraordinary indices of refraction less than the substrate such that mode mismatch between a device fabricated thereby and an externally coupled fiber is reduced. The aluminum can be diffused into LiNbO.sub.3 at a much lower temperature without affecting diffused titanium guides. Preferably, the titanium diffusion occurs at about 1000.degree. to about 1100.degree. C. while further aluminum diffusion occurs at a lower temperature in the range of about 900.degree. to 950.degree. C.

Abstract: An optical modulator comprises a crystal whose top surface includes a channel waveguide whose axis makes an angle with the crystal optic axis larger than the critical angle for TE-polarized leaky mode propagation. An electrode structure overlies the top surface of the crystal for inducing mode conversion of TM-polarized waves propagating in the waveguide to lossy radiation modes.
