Abstract

End surface grating by direct inscribing an index modulation pattern on optical waveguide surface to control amplitude and direction of the diffracted light is fabricated. Direct inscribing an index modulation pattern by femto-laser is simple, agile and the pattern is steady and durable. We control power and direction of diffracting orders by inscribing different modulation patterns and the controllability may well offer opportunities for various kinds of applications such as beam splitter, beam deflector, and beam shape controller.
