In this work we present the fabrication process of channel waveguides by ionic exchange on a glass substrate. To delimit the channel areas on the glass substrate two procedures are used. The first one is by conventional lithography, making use of an aligner, photoresist and a mask. The second consists in implementing a holographic interferometer to imprint on the photoresist layered substrate, a straight fringes interference pattern of desired period. The glass index increasing in the channels area is obtained by Na+/K+ ionic interchange. We present the near field characterization results of the waveguides fabricated by the conventional method; as well as results of the parameters optimization and grids, fabricated by the holographic method.
