Paper Abstract

We propose and demonstrate an interferometric method of fabricating one-dimensional (1D) and two-dimensional (2D) periodic structures on planar substrates. The central idea of the method is to match the substrate or fiber translation velocity to that of the moving interference pattern so as to create its stationary image on the substrate or fiber. The moving interference pattern is produced by phase control of multiple interfering beams. The pitch of the structures can be changed by adjusting the frequency shifts between the interfering beams, and we demonstrate this pitch control technique in the case of interferometrically written 1D periodic structures. There is no limitation on the grating length, and grating designs can be arbitrarily complex optimized for use in both planar and fiber Bragg grating laser resonators.
