摘要： Methods and apparatus provide for birefringent waveguides suitable for optical systems exhibiting polarization dependence such as interferometer sensors including Sagnac interferometric fiber optic gyroscopes (IFOG). The waveguides, for some embodiments, may offer single polarization performance over lengths of about a kilometer or more due to polarization dependent attenuation. According to some embodiments, the waveguides incorporate a pure silica core for resistance to radiation-induced attenuation (RIA).

摘要： We introduce a mechanically tunable photonic crystal structure consisting of coupled photonic crystal slabs. Using both analytic theory, and first-principles finite-difference time-domain simulations, we demonstrate that the transmission and reflection coefficients for light normally incident upon such structures can be highly sensitive to nano-scale variations in the spacing between the slabs. Moreover, by specifically configuring the photonic crystal structures, the high sensitivity can be preserved in spite of significant fabrication-related disorders. We expect such a structure to play important roles in micro-mechanically tunable optical sensors and filters.

摘要： Disclosed are an optical fuse and a device for fabricating such an optical fuse. The optical fuse comprises a medium constituting a structure in which a light-emitting end of a first optical waveguide is coupled to a light-incident end of a second optical waveguide across the medium, and a light-absorbing body adapted to absorb the light. The medium is transparent to light passing through the structure, and the light-absorbing body is disposed in contact with an outer peripheral surface of the medium in such a manner as to allow a part of light emitted from the light-emitting end into the medium to reach the light-absorbing body. The optical-fuse fabricating device comprises a pair of first and second support members formed, respectively, with first and second through-holes for supporting an optical fiber, and a beam member mechanically connecting the first and second support member together. When the first and second support members are arranged such that respective axes of the first and second through-holes are aligned in a straight line to allow a single common optical fiber to be inserted into both the first and second through-holes, a spacial gap is formed between the single common optical fiber and the beam. The present invention can provide an optical fuse having a low insertion loss and allowing an optical coupling to be eliminated in response to an irreversible change induced therein, and a device capable of allowing such an optical fuse to be fabricated in a simple and easy way.

摘要： An optical fiber array is provided in which an optical fiber tip end is housed in a holding member (2). The holding member (2) consists of a substrate (3) and a cover plate (5). The substrate (3) forms a sectional V shaped housing groove (4) for housing the optical fiber (1) on a top face. The cover plate (5) covers the top face of the substrate (3). An adhesive is filled between the substrate (3) and the cover plate (5) which fixes optical fiber (1) in the housing groove. A distance Y between the substrate (3) and the cover plate (5) is L / 6≦Y≦L, with Y being the thickness of the adhesive layer and L being a distance from a contact point (P) between the housed optical fiber (1) and the housing groove (4) to the cover plate (5). In this manner, even under severe environmental conditions, a release or delamination of the holding member (2) is not likely to occur, and good optical coupling characteristics can be maintained.

摘要： An optical coupler converts a light distribution from a light source into a small angle distribution that extends over a volume larger than the variations in the alignment of an optical fiber. In one embodiment, a diffractive or hybrid diffractive/refractive bifocal lens forms first and second images of the light source respectively in first and second image planes. An input face of the optical fiber is between the first and second image planes and receives light diverging from the first image plane and light converging toward the second image plane. The net optical power coupling into the fiber is uniform over a large range of fiber positions and provides the optical coupler with a relaxed tolerance for misalignment of the fiber or the light source. The relaxed alignment tolerance facilitates low cost manufacture of multi-channel optical transmitters using single-mode optical fibers.

摘要： The present invention is directed to a method and an apparatus for analysis of an analyte. The method involves providing a zero-mode waveguide which includes a cladding surrounding a core where the cladding is configured to preclude propagation of electromagnetic energy of a frequency less than a cutoff frequency longitudinally through the core of the zero-mode waveguide. The analyte is positioned in the core of the zero-mode waveguide and is then subjected, in the core of the zero-mode waveguide, to activating electromagnetic radiation of a frequency less than the cut-off frequency under conditions effective to permit analysis of the analyte in an effective observation volume which is more compact than if the analysis were carried out in the absence of the zero-mode waveguide.
