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.

A method for processing a ferrule for a fiber optic connector is disclosed herein. The ferrule supports an optical fiber. The method involves laser processing a distal end of the ferrule to expand at least a portion of the ferrule to cause recession of an end of the optical fiber relative to the expanded portion of the ferrule.

An optical path conversion component includes a light-transmitting member; one or plurality of lenses; one or plurality of optical waveguides; and a formed part. The light-transmitting member has a first surface and a second surface that forms an angle of less than 90 with the first surface, and includes a region made of glass. The one or plurality of lenses are provided on the second surface. The one or plurality of optical waveguides are provided in the region, and are optically coupled to the one or plurality of lenses, respectively. The formed part is provided on the second surface, and contains a same constituent material as a constituent material of the one or plurality of lenses. The formed part has a surface parallel to any surface among outer surfaces of the light-transmitting member except for the second surface.
