An array of corresponding passive optical elements is interposed between the plurality of LED dies and the corresponding first ends of the plurality of optical waveguides. The illumination system provides for substantially high light coupling efficiency and an incoherent light output that can appear to the human observer as arising from a single point of light.

The present invention is an optical harness and method for an optical cross-connect. The optical harness is defined primarily by a first portion and a second portion. The first portion of the optical harness comprises a number M of fiber optic row cables where each fiber optic row cable comprises an array of a number N of fiber optics arranged on a first plane. The first plane on which each fiber optic row cable is disposed is substantially parallel to each of the other first planes on which a fiber optic row cable is disposed. The second portion of the optical harness comprises a number N of fiber optic column cables where each fiber optic column cable comprises an array of a number M of fiber optics arranged on a second plane. Each fiber optic column cable is disposed on a second plane being substantially parallel to each of the other second planes on which each other fiber optic column cable is disposed. The optical harness further comprises a holding mechanism disposed intermediate the first portion and the second portion of the optical harness. The orientation of the first planes on which the fiber optic row cables are disposed is arranged at a defined angle relative to the second plane on which the fiber optic column cables are disposed. The holding mechanism is arranged and configured to transition the fibers from one configuration toward the first portion to the second configuration toward the second portion and to prevent the separation of the fibers from the optical fiber row cables from progressing toward the first portion of the optical harness. The method for providing an optical cross-connect between a first element and a second element comprises providing the optical harness with connectors disposed on free ends of each of the fiber optic row cables and each of the fiber optic column cables. The fiber optic row cable connectors can be placed in communication with first element, and the fiber optic column cable connectors can be placed in communication with the second element.

An optical fiber array (10) is provided with a board (30) whereupon storing grooves (34) for storing optical fibers (24) are formed, a cover plate (12) for covering the optical fibers (24) stored in the storing grooves (34), and an adhering layer (16) for bonding the board (30), wherein the optical fibers (24) are stored in the storing grooves (34), with the cover plate (12). On the board (30), adhering grooves (36), into which the adhering layer (16) is applied, are formed between the storing grooves (34) which store the optical fibers (24) and the edge part of the board (30). The adhering grooves (36) are formed in V-shape and almost parallel to the storing grooves (34). The adhering grooves (36) (an adhering groove (36a)) are formed in the vicinity of an outermost storing groove (34a) among the storing grooves (34), and in the vicinity of the edge part of the board (30) (an adhering groove (36b)). At least one adhering groove (36) is preferably formed between the outermost storing groove (34a) among the storing grooves (34) and the edge part of the board (30), and a plurality of the adhering grooves may be formed.

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.

A fiber optic backplane (20) has a casing portion (22) and multiple fiber optic ribbons (28) that extend from the same location (32) of the casing portion. One arrangement includes multiple optical fibers (26), a casing (22) and a set of ribbon coatings (24). The casing holds casing portions of the optical fibers. The set of ribbon coatings (24) holds ribbon portions of the optical fibers in rows to form multiple optical fiber ribbons. Each ribbon coating of the set of ribbon coatings attaches to the casing at a same location (32) of the casing such that the optical fiber ribbons extend from the same location of the casing. The multiple optical fiber ribbons extending from the same casing location enable higher optical fiber densities than conventional fiber optic backplanes which only have parallel ribbon portions extending from different locations (e.g., centimeters apart) of a central backplane portion.

An optical fiber array comprises an upper substrate 32 and a lower substrate 31 in which V-shaped grooves 33 are formed, wherein optical fibers 38 are inserted and arranged in the V-shaped grooves 33 and are solidified using an adhesive. The lower substrate 31 comprises a V-shaped groove section having V-shaped grooves 33 in which the optical fibers 38 are aligned and arranged, a covered optical fiber support section 35 for supporting covered optical fibers 36a and 36b, and a free buffer section 34 located between the V-shaped groove section and the covered optical fiber support section 35 and that is prevented from restricting the alignment and arrangement of the optical fibers 38, wherein the free buffer section 34 continues with the covered fiber support section 35 via a step. The optical fiber array allows the positional relationship between an uncovered optical fiber and a covered optical fiber to be set accurately, that can prevent its characteristics from being degraded, and that can avoid problems such as an open circuit in the fibers.

The invention relates to a pigtailing method, i.e., the invention provides an optical device comprising a substrate on which are integrated a layered optical waveguide component (3) and optical fibre ends (13). The optical fibre ends are positioned in grooves (10). The method involves providing a substrate (7) comprising grooves (10), notably V-shaped grooves, with a separately made optical waveguide component (3). The component (3) is made on a separate flat substrate (1) and released by virtue of a releasable layer (2) present on the flat substrate (1). An advantageous releasable layer is made of a water-soluble salt. The invention also pertains to flexible waveguide sheets (3) such as can be used in the above method or, if provided with waveguide channels (12), as flexible waveguide components themselves.
