    Abstract: A ferrule with fiber holes includes: a resin-molded portion molded by a resin; and a reinforcement member embedded in the resin-molded portion and that has a smaller linear expansion coefficient than the resin-molded portion. The reinforcement member includes fiber insertion portions that are parallel to the fiber holes. The fiber holes are formed by the resin that entered the fiber insertion portions.

    Abstract: An optical connector system includes: an optical path-changing device including a fiber-holding part that holds a single-mode optical fiber along a first direction, and a reflection surface that reflects an optical signal; and a relay device on a substrate. The substrate includes a grating coupler for inputting/outputting an optical signal in a second direction that is inclined with respect to a direction perpendicular to a surface of the substrate. The optical path-changing device and the relay device each have an input/output surface to/from which the optical signal is inputted/outputted. A first convex lens is disposed on the input/output surface of the optical path-changing device. A second convex lens is disposed on the input/output surface of the relay device.

    Abstract: Disclosed is an optical-connector fixing member including: an upper plate part for pressing, toward a receptacle provided on a substrate, a ferrule that holds an end section of an optical fiber; and a pair of engagement side plate parts formed so as to extend from the upper plate part toward the substrate, each engagement side plate part having a connector-side engagement section that engages with a receptacle-side engagement section formed on a side surface of the receptacle. An engaged state in which the connector-side engagement section is engaged with the receptacle-side engagement section is releasable by inserting an end section of a tool into a gap between each engagement side plate part and a member that is arranged between the pair of engagement side plate parts, and spreading each engagement side plate part outward.

    Abstract: A ferrule of the present invention includes a positioning mechanism for positioning an optical fiber, and a recess having at least a first inner wall for allowing a front end of the optical fiber portion positioned by the positioning mechanism to protrude, and a second inner wall opposite to the first inner wall. A distance between the first inner wall and the second inner wall is less than or equal to four times the outer diameter of the optical fiber. Adhesive is filled into the recess and cured in a state in which the optical fiber protrudes from the first inner wall and substantially contacts the second inner wall to fix the optical fiber.
