Assemblies, optical connectors and methods of bonding optical elements to substrates

Abstract:

Assemblies, optical connectors, and methods for bonding optical elements to a substrate using a laser beam are disclosed. In one embodiment, a method of bonding an optical element to a substrate includes disposing a film layer on a surface of the substrate, disposing the optical element on a surface of the film layer, and directing a laser beam into the optical element. The method further includes melting, using the diameter laser beam, a material of the substrate to create a bond area between the optical element and the surface of the substrate. The film layer is capable of absorbing a wavelength of the laser beam to melt the material of the substrate at the bond area. The bond area includes laser-melted material of the substrate that bonds the optical element to the substrate.
