ABSTRACT:
An optical device, such as optical coupling devices, optical switches, optical isolators, optical attenuators, laser diodes, photo diodes are provided having a substrate with a groove in order to locate a optical fiber. A lens, such as a graded index lens, is secured to the end of the optical fiber, with the lens located outside the groove, thereby avoiding difficulties with axial alignment of the lens caused by the interface of the optical fiber to the lens. In one implementation, the groove in the prototype is a V-groove, thereby providing stable positioning of the optical fiber within the groove.
