  • Fibre stub device and method using butt coupling for receptacled photonic devices
    Patent number: 9897770
    Abstract: A novel, hybrid optical fiber stub device comprises a first ferrule transparent to UV light and a second ferrule including a conventional material. An optical fiber is disposed through the first ferrule and second ferrule. The input and output faces of the optical fiber are prepared suitable for optical coupling. A photonic device is coupled to the first optical fiber surface. A UV curable epoxy is disposed between the photonic device and the first optical fiber surface. The UV curable epoxy includes an index of refraction between an index of refraction of the first optical fiber and an index of refraction of the photonic device. A second optical fiber is coupled to the first optical fiber.
