Blockless fiber attachment assembly for optical devices

摘要

An optical fiber attachment assembly and method of making such an assembly. The assembly includes an optical device having an optical waveguide with an end surface exposed on an end surface of the device, and a bare optical fiber having an end surface cleaved at a predetermined angle and aligned with the end surface of the waveguide. The end of the fiber is affixed to the optical device by a first adhesive. A strain relief block positioned at a distance from the end surface of the optical device and the optical fiber is affixed to the strain relief block by a second adhesive to securely mount the fiber to the optical device. The optical device and the strain relief block are mounted on a carrier. Also described is a method for attaching an optical fiber to a waveguide in an optical device. The fiber attachment assembly and method can be used in a flip-chip configuration where the chip is mounted on a ground plane in a flipped orientation via a plurality of spacers.
