A fiber optic connector includes polymeric material arranged within a front end portion of at least one internal bore of a ferrule. At least a portion of the polymeric material extends from a terminal end of at least one optical fiber to at least a front end of the ferrule. A polymeric material end face serving as a conduit for transmitting optical signals to and/or from the at least one optical fiber. Waveguiding regions may be incorporated in polymeric material assemblies. Polymeric material may be printed, dispensed, or otherwise applied over the terminal end of the at least one optical fiber in the at least one internal bore, and subsequently cured. Polymeric material arranged over (e.g., in contact with) the terminal end of an optical fiber may reduce or eliminate the need for fiber end face polishing, and creates physical contact through an optical interface without exerting undue mechanical stresses on the optical fiber.

Fiber optic connector with polymeric material between fiber end and ferrule end, and fabrication method

Optical interconnection assemblies, glass interconnection substrates, and methods for making optical connections are disclosed. In one embodiment, an optical interconnection assembly includes a base substrate, a substrate optical waveguide coupled to the base substrate, the substrate optical waveguide having an end surface, an optical chip comprising an optical coupling surface, and a glass interconnection substrate. The glass interconnection substrate includes a first end optically coupled to the end surface of the substrate optical waveguide, a second end optically coupled to the optical coupling surface of the optical chip, and a curved portion disposed between the first end and the second end. The glass interconnection substrate further includes an optical waveguide at least partially positioned within the curved portion.

Optical interconnection assemblies, glass interconnection substrates, and methods of making an optical connection

A fiber coupling device for coupling of at least one optical fiber is disclosed. The fiber coupling device comprises at least one opto-electronic and/or photonic chip comprising at least one opto-electronic and/or photonic integrated element capable of emitting and/or detecting electromagnetic radiation. The fiber coupling device is configured for coupling the at least one opto-electronic and/or photonic integrated element to at least one fiber end-piece of an optical fiber having a reflection surface and a convex exit and/or entrance surface. The fiber coupling device further comprises a fiber end-piece alignment substrate configured for locally contacting and thereby supporting at least one convex exit and/or entrance surface of at least one fiber end-piece in an aligned position relative to the at least one opto-electronic and/or photonic integrated element.
