摘要:
A method of manufacturing a molded optical channel waveguide (11), having a critical internal reflection angle and an exposed surface (17), and affixing a holographic layer (16), having gratings (20) formed therein, in overlying relationship with the exposed surface of the optical waveguide. The gratings being positioned to form an angle (a) with the surfaces of the holographic layer such that light rays incident on an upper surface of the holographic layer and substantially normal thereto are diffracted by the gratings into the optical waveguide. Also, light waves travelling within the waveguide couple outwardly through the holographic layer. Light generators (51) and detectors (52) are mounted to supply light to and receive light from the holographic layer.

An optical link having a terminal (15, 20) at each end, each terminal including formatting circuitry (25, 50) controllable to format transmitted data in a variety of configurations and to rectify formatting errors and failure detectors (40, 60) for detecting the failure of an optical path and switching to a properly operating redundant path.

An adjoining waveguide (104) and optical connector (102) is provided. A waveguide (104) including a first end surface (123), a second end surface (124), and an adjoining surface (118) is formed. The adjoining waveguide (104) further includes a core region (108) that extends from the first end surface (123) to the second end surface (124) and a cladding region (105) that surrounds the core region (108). The first end surface (123) and the second end surface (124) of the waveguide (104) exposes a portion of the core region (108) that is used for optical coupling. The joining surface (108) forms an interconnecting surface for another waveguide (106).
摘要:
An optical bus (10) including two identical transceiver modules (12) each including transmitter and receiver circuitry and light detectors and light generators (70). The light detectors and generators (70) are coupled, optically, to the ends of an optical fiber ribbon (13) by a molded waveguide (40) and, electrically, to the transmitter or receiver by conductors (26, 31, 32) in a mounting board (25). The receiver circuitry contains a burst mode, non-linear receiver (80) and the transmitter contains CMOS circuits (38) to increase the simplicity and speed of the module.

摘要:
An optical interface including a keyway (20) formed in a printed circuit board (16,17) and a mating portion (22) attached to the ends of a plurality of optical fibers (28). Openings (24) in a surface (25) of the keyway (20) communicate light from the fibers (28) to semiconductor chips (14) on the board (16,17) by means of optical waveguides formed in the dielectric layers (17) of the printed circuit board (16,17). The keyway (20) accurately aligns the mating portion (22) which aligns the ends of the fibers (28) with the openings (24).
摘要:
A method of coupling an optical fiber (20) to a desired optical input (15) (e.g. an integrated optical waveguide) wherein the optical fiber (20) is pre-coated with a magnetic material (21) and then placed in an elongated groove (12) in a base (10), one end of which groove (12) terminates at the desired optical input (15). A magnetic field is applied to hold the pre-coated optical fiber (20) firmly in place while it is permanently mounted by some means such as soldering or an adhesive.
