Abstract: The liquid-assisted micromachining methods include methods of processing a substrate made of a transparent dielectric material. A working surface of the substrate is placed in contact with a liquid-assist medium that comprises fluorine. A focused pulsed laser beam is directed through a first substrate surface and through the opposite working surface to form a focus spot in the liquid-assist medium. The focus spot is then moved over a motion path from its initial position in the liquid-assist medium through the substrate body in the general direction from the working surface to the first surface to create a modification of the transparent dielectric material that defines in the body a core portion. The core portion is removed to form the substrate feature, which can be a through or closed fiber hole that supports one or more optical fibers. Optical components formed using the processed substrate are also disclosed.

Abstract: Receptacle ferrules with at least one monolithic lens system and fiber optic connectors using same are disclosed. Ferrule assemblies formed by mating plug and receptacle ferrules are also disclosed, as are connector assemblies formed by mating plug and receptacle connectors. The fiber optic connectors and connector assemblies are suitable for use with commercial electronic devices and provide either an optical connection, or both electrical and optical connections. The monolithic optical system defines a receptacle optical pathway having a focus at the receptacle ferrule front end. When a plug ferrule having a plug optical pathway is mated with the receptacle ferrule, the plug and receptacle optical pathways are optically coupled at a solid-solid optical pathway interface where light passing therethrough is either divergent or convergent, and where unwanted liquid is substantially expelled.
