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.

The sets of first, second, and third waveguide segment confinement parameters are configured to, collectively, maximize a predetermined worst-case optical-loss performance level of the asymmetric optical-loss performance curve within a range of waveguide fabrication tolerances.

A parallel position manipulator includes a top plate, a baseplate and a plurality of prismatic joint actuators. Each actuator includes an actuator joint having five Degrees of Freedom (DOF) at either the base plate or the top plate. When one or more of the actuators extends or contracts, the pivot points, or five DOF actuator joint, of the remaining actuators are allowed to shift in any axis other than that actuator's primary axis of motion.

A method and device for interconnecting optical components, such as optical fibers and optical circuits, in a flexible, repeatable, and cost-effective manner. Two or more optical components are interconnected by a flexible optical circuit substrate bearing one or more embedded optical fibers with a lens at each end of each fiber. The flexible optical circuit may be incorporated into a housing bearing apertures for receiving the optical connectors of the optical components that are to be interconnected with the device. The lensed ends of the fibers embedded in the flexible optical circuit are positioned adjacent to the apertures for optically connecting to the fibers within the connectors installed in the apertures without conventional mating connectors disposed inside the housing.

An optical module includes a housing; an optical adapter arrangement disposed at the housing; a cable inlet leading from an exterior of the housing to the interior of the housing; and a splice location disposed within the interior of the housing. Optical pigtails extend from the optical adapter arrangement to the splice location.
