Method of making micro-optical components on polydiacetylene optical devices
 A method of making Y couplers and grating optical waveguides of the present invention comprises exposing the polydiacetylene to an e-beam or a similar exposing means causing a change in the index of refraction of the polydiacetylene. In the case of e-beam exposure, the optical component patent is produced by directly controlling the e-beam which does not require any physical and/or chemical preparation of the polydiacetylene. The depth of penetration of the e-beam is controlled by the scanning rate and intensity of the e-beam. The optical gratings, fabricated by e-beam exposure technique, also inherit nonlinear optical properties which can be utilized in nonlinear optical applications.
