A portion of the one or more optical fibers that is in contact with the support may be bent. This method, and fiber optic devices made using this method are more easily aligned and may be produced at lower costs than existing manufacturing processes. | 05-14-2015 |
20150309272 | OPTICAL CONNECTORS FOR COUPLING LIGHT SOURCES TO OPTICAL FIBERS - Optical connectors for connecting optical fiber to a light source are disclosed. In one embodiment, an optical connector includes a housing with a first end having an open aperture and a second end having a blind aperture. A chamber is disposed in the housing such that the optical axis of the housing passes through the chamber. The chamber includes a first material. A light collecting region formed from a second material is disposed in the housing between the second end of the housing and the chamber. A blind aperture is positioned in the light collecting region such that a termination of the blind aperture is spaced apart from the chamber by at least a portion of the second material. A refracting surface is disposed in the housing between the open aperture and the light collecting region such that the optical axis of the housing passes through the refracting surface. | 10-29-2015 |
20150323750 | Alignment Jig for Optical Lens Array - An alignment jig for an optical lens array is furnished on an optical alignment apparatus. The alignment machine is for performing active optical alignment operations of a sensor chip located on a circuit board and a lens socket plugged with a fiber plug. The alignment jig includes a support arm, a pick-up mechanism and a pushing mechanism. The support arm is fixed to the optical alignment apparatus for supporting the alignment jig. The pick-up mechanism is furnished on the support arm for picking-up and holding the lens socket in a detachable manner at a predetermined position corresponding to the sensor chip. The pushing mechanism holds the plugging status when the fiber plug is plugged into the lens socket and provides a pushing force, such that the fiber plug has a tendency to be pushed toward and engage the lens socket tightly. | 11-12-2015 |
