Abstract
A method for creating a random anti-reflective surface structure on an optical fiber including a holder configured to hold the optical fiber comprising a groove and a fiber connector, an adhesive material to hold the optical fiber in the holder and fill any gap between the optical fiber and the holder, a glass to cover the adhesive material and the optical fiber, and a reactive ion etch device. The reactive ion etch device comprises a plasma and is configured to expose an end face of the optical fiber to the plasma. The plasma is configured to etch a random anti-reflective surface structure on the end face of the optical fiber.
