Methods for laser bonding optical elements to substrates and optical assemblies are disclosed. According to one embodiment, a method of bonding an optical element to a substrate includes disposing at least one optical element onto a surface of the substrate, electrostatically affixing the at least one optical element to the surface of the substrate, and directing a laser beam into the at least one optical element. The laser beam heats an interface between at least one optical element and the substrate to a temperature that is higher than a lowest temperature of the optical element change temperature and the substrate change temperature, thereby forming a bond between at least one optical element and the substrate at a bond area. The laser beam has a fluence that does not modify the substrate at areas of the substrate that are outside of the at least one optical element.

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.
