ABSTRACT:
Fiber stub interface for reducing cladding mode light. The fiber stub can be implemented in an optical transmission device. The optical transmission device can be a transceiver that also includes an optical signal receiver. The fiber stub includes an optical fiber and a ferrule. The optical fiber includes both a core and a cladding. The ferrule includes a glass material with a refractive index that is greater than the refractive index of at least a portion of the optical fiber. As a result, the cladding modes are refracted into the ferrule and away from the core, thereby reducing the chance that they are transmitted to an external optical fiber. An absorptive layer can be applied to an outer surface of the ferrule to absorb the refracted cladding modes.
