The surface includes a normal direction parallel with the first direction. A first length of the engaging section of the optical fiber protruding from the surface of the installation portion is longer than lengths of the elements protruding from the surface.

Apparatuses, systems and methods for optical coupling, optical integration, electro-optical coupling, and electro-optical packaging are described herein. Optical couplers may comprise various optical elements (e.g., mirrors as described herein) to relax optical assembly requirements and improve producibility. Optical couplers may improve fiber-to-chip, fiber-to-fiber and chip-to-chip optical connection. Optical couplers and optical components may be used to improve integration of, connection of, and/or packaging of optical systems and/or components with electrical systems and/or components.

An optical connector has a connector housing assembly for holding one or more ferrules, the connector housing assembly having a height align a vertical alignment axis and a width perpendicular to the height. The connector housing assembly includes an inner front body and an outer release component, the outer release component being movable in relation to the inner front body between a front position and a back position. The optical fiber connector is configured to mate with a receptacle having an upper receptacle hook such that the upper receptacle hook is received in the upper receptacle hook recess and latches with the upper hook retainer surface when the outer release component is in the front position and such that the upper ramp lifts the upper receptacle hook out of the upper receptacle hook recess when the outer release component moves to the back position.

An optical fiber coupling connector includes a board, a light receiving device, two light emitting devices, a controller and an optical coupling lens. The optical coupling lens includes three main bodies, each includes a bottom surface, a top surface, an alignment surface, a first and a second side surface, a third side surface obliquely connected to the first side surface, and a fourth side surface obliquely connected to the second side surface and connected to the third side surface at a second edge. The alignment surface, the first side surface, the third side surface, the fourth side surface and the second side surface are connected to each other end to end in that order. The third side surface of each one of the main bodies contacts the fourth side surface of an adjacent one of the main bodies. At least three optical fibers positioned to the optical coupling lens.

A termination ferrule includes a ferrule body and a ferrule plate. The ferrule body includes multiple bores arranged to align with a pattern of lasers in a vertical-cavity surface-emitting laser (VCSEL) array. Each of the multiple bores includes an entry diameter sized for an optical fiber with a protective coating and an exit diameter sized for a portion of the optical fiber without the protective coating. The ferrule plate includes multiple holes arranged to align with the pattern of lasers in the VCSEL array. Each of the multiple holes includes a hole diameter sized to receive the portion of the optical fiber without the protective coating. The ferrule plate is secured between the VCSEL array and the ferrule body, and the ferrule plate includes a thickness sufficient to create a gap between each laser in the VCSEL array and the corresponding optical fiber.

This optical module comprises a substrate, light-emitting elements, a ferrule, an optical receptacle, through-holes and an adhesive. The optical receptacle includes two support units, and an optical receptacle body that has a first optical surface and a second optical surface. The through-holes include two first through-holes surrounded by the leading ends of the support units and the ferrule, and two second through-holes which are surrounded by the optical receptacle body, the support units and the ferrule. Thus, even using the adhesive to fix the optical receptacle and the ferrule to the substrate, it is possible to optically connect multiple optical transmission bodies with multiple light-emitting elements or multiple light-receiving elements in a suitable manner.
