摘要:
An apparatus for coupling two optical elements comprises a plurality of optical fibers, a plurality of first substrates stacked in a first direction, and a plurality of second substrates stacked in a second direction perpendicular to the first direction. Each optical fiber is fixed to one of the first substrates and a corresponding one of the second substrates such that none of the optical fibers cross over one another.

Optical coupling systems are provided. An optical coupling system includes a first optical fiber end having a first core, a second optical fiber end having a second core, and a laser diode optically coupled to the first core and the second core at an optical coupling location. The laser diode emits a light beam having an asymmetrical cross-sectional light beam profile comprising a fast axis diameter and a slow axis diameter. The fast axis diameter is longer than the slow axis diameter. Further, the first optical fiber end and the second optical fiber end are adjacently positioned along the fast axis diameter of the asymmetrical cross-sectional light beam profile of the laser diode at the optical coupling location such that the first core and the second core are within the asymmetrical cross-sectional light beam profile at the optical coupling location.

A coherent fiber array (310) is used to optically detect a radiometric event. The coherent fiber array has a dome-shaped detection surface (340) and a planar output surface (350). Optical energy from the radiometric event is detected at the dome-shaped detection surface and transferred to the output surface. The coherent fiber array retains directionality of the radiometric event while transferring the optical energy from the detection surface to the output surface.

An optical fiber array substrate (11) has on its one surface eight V-shaped grooves (12) for fixing 8-core optical fibers (14) arranged in parallel to one another and V-shaped side groove portions (13) formed outside of the outermost V-shaped grooves (12) located in the vicinity of the both sides of the substrate (11). The outer heaps (12c, 12d) forming the outermost V-shaped groove (12) have a summit of an identical height to the summit (12a) of the inner heap and the bottom (13a) of the side groove portion (13) has a height lower than the contact point (12e) between the ridge of the V-shaped groove (12) and the optical fiber (14).

A photon emitting device comprises a plurality of solid state radiation sources to generate radiation. The solid state radiation sources can be disposed in an array pattern. Optical concentrators, arranged in a corresponding array pattern, receive radiation from corresponding solid state radiation sources. The concentrated radiation is received by a plurality of optical waveguides, also arranged in a corresponding array pattern. Each optical waveguide includes a first end to receive the radiation and a second end to output the radiation. A support structure is provided to stabilize the plurality of optical waveguides between the first and second ends. The photon emitting device can provide a replacement for a discharge lamp device in various applications including road illumination, spot lighting, back lighting, image projection and radiation activated curing.

A three dimensional optical circuit featuring an optical manifold (200) for organizing, guiding and protecting individual optical fibers is shown. The manifold has a number of input openings (210) in a first ordered arrangement at one end connected by passageways to a number of output openings (220) in a second ordered arrangement at the opposite end. A plurality of optical fibers may be directed through the passageways of the manifold to produce a three dimensional optical circuit such as a shuffle. The optical manifold may be used in conjunction with a number of connections or terminations to form a various optical modules. These modules may be configured for rack mounting within enclosures for electrical components.

An optical fiber array substrate 11 has, in one surface thereof, eight V-grooves 12 for securing eight optical fibers 14 aligned in parallel to each other, and V-shaped side grooves 13 formed outside of the respective outermost V-grooves 12 located at the opposite sides of the substrate 11. The apexes of the outside ridges 12c and 12d defining the outermost V-grooves 12 are at the same height as the apexes of the inside ridges 12a and, the height of the bottom 13a of the side groove 13 is lower than that of a contact point 12e between the ridge line of the V-groove 12 and optical fiber 14.

A fanout connector (20) is provided for a fiber optic cable (28) including a plurality of optical fibers (30). The connector includes a housing means (22,24) having a passage (34) for receiving the fiber optic cable transversely along an axis (36). A fanout member (26) in the housing spreads the individual optical fibers (30) of the cable (28) transversely of the axis (36). At least one frangible mounting member (64) is provided on the housing means for mounting the connector on an appropriate support structure. The mounting member (64) is readily breakable from the housing when the connector is to be used as a stand-alone unit. The housing includes a base (22) and a cover (24) with complementary interengaging polarizing members (92,94) between the base and the fanout member. The cover (24) has a transparent window (80) to afford visual inspection of at least a portion of the cable within the housing.
摘要:
The present invention aims to prevent formation of defect or break-off at ridges of fixing grooves of optical fiber-fixing substrates (1) when an optical fiber is received in the fixing groove (3) or when an end surface of the substrate is polished by a grinding work. For that purpose, the ridges (4) of the fixing grooves of the substrate have a curvature of radius of not less than 5 µm over the entire portion of the ridges viewed in the lateral cross-sectional view of the fixing grooves. Preferably, the bottoms of the fixing grooves of the substrate have a curvature of radius of not more than 5 µm viewed in the lateral cross-sectional view of the fixing groove. The fixing grooves may be produced by press forming.
