Abstract:
An optical receptacle and an optical module that implements the optical receptacle are disclosed. The optical receptacle provides a stub holding a coupling fiber in a center thereof, a bush press-fitting the stub therein, a sleeve, and a metal cover that is to be welded to an external metallic member. The coupling fiber has a type of polarization maintaining fiber. The bush is inserted into the cover as leaving a gap between the cover and the bush. The gap between the cover and the bush effectively relaxes or absorbs stresses induced during the welding caused in the coupling fiber.
Abstract:
A connector plug arrangement (330, 600, 700) includes a connector body (334, 610, 720); and an indication component (335, 650, 750). The indication component (335, 650, 750) includes a first portion (337, 653, 751) that is disposed at a rear end of the connector body and a second portion (339, 654, 753) that extends outwardly from the first portion (337, 653, 751). The first portion (337, 653, 751) is configured to extend along a circumferential perimeter of the connector body (334, 610, 720). The second portion (339, 654, 753) is configured to extend along the longitudinal axis of the connector body (334, 610, 720).
Abstract:
Methods for manufacturing and using an optical or optoelectronic device are disclosed. The optical or optoelectronic device and related methods may be useful as an optical or optoelectronic transceiver or for the processing of optical signals. The optical or optoelectronic device generally comprises a light-transmitting medium configured to transmit a first light beam; a light-receiving unit configured to receive and process a focused, reflected light beam; a first mirror or beam splitter configured to reflect at least a first portion of the transmitted light beam away from the light-receiving unit; a lens configured to focus the reflected light beam; and a second mirror configured to reflect the focused, reflected light beam towards the light-receiving unit.

Abstract:
A method is disclosed to provide improved fiber inline optical power monitoring that eliminates the need for micro-bending the fiber or for fabricating micro-reflector on the fiber. A subset of light is tapped through an offset at a fusion-spliced upstream and downstream optic fiber, and is guided out of the downstream fiber by a light guide to a reflector and photo-sensing measurement. The disclosed inline fiber monitoring is thus cost effective, wavelength independence, reliable, stable, and also causes less light transmission loss.

Abstract:
A device for bending an optical fiber and receiving light is provided with a recessed holding member having a recess, a projecting holding member having a projection projecting toward the recess, light receiving elements for receiving leak light from an optical fiber held between the recess and the projection, and a supplemental support mechanism that is substantially independent of the recess or the projection and supplementarily supports the optical fiber between the recess and the projection such that the leak light from the optical fiber is received by center of the light receiving elements.
Abstract:
Photonic structures and methods of formation are disclosed in which a photo detector interface having crystalline misfit dislocations is displaced with respect to a waveguide core to reduce effects of dark current on a detected optical signal.
Abstract:
An optical module includes a package, a substrate, a lead pin, and a ground pattern. The substrate is accommodated in the package, includes a signal line pattern that transmits an electric signal, extends toward a side wall of the package beyond an end of the signal line pattern, and has a through hole between the end of the signal line pattern and the side wall of the package. The lead pin is inserted into the through hole in the substrate and inputs the electric signal to the end of the signal line pattern. The ground pattern is provided in at least a part of regions surrounding the through hole on the substrate.
Abstract:
An optical module includes: a substrate provided with a through hole for inserting an optical fiber from a second principal surface side of the substrate; an optical device provided on a first principal surface side of the substrate; a first electrode provided in the substrate for connecting an electric fiber from the second principal surface side; a second electrode formed on the first principal surface side of the substrate for connecting to the optical device; and a third electrode provided on a side surface of the substrate and electrically connected to the second electrode.
