Patent image
NRL

This invention pertains to fiber termination combination which includes an optical fiber having a fiber core for transmitting a highly energetic optical signal that can damage the fiber and a structured region around the core for directing the optical signal into the core, the structured region being characterized by multiple channels of smaller internal diameter than the core defined by thin walls disposed around said core; a ferrule, with an opening therein for locating said fiber, at the end of said fiber enveloping said fiber extremity which cooperates with said blocking structure to block the optical signal from impinging on said microstructured region of said fiber; and a blocking structure disposed over the end of said fiber with an opening mating with said fiber core, said blocking structure blocking the optical signal from impinging on said microstructured region of said fiber.
