摘要:

We introduce a simple fabrication technique of nonlinear polymeric optical waveguide patterns based on the holographic method. It is found that the second-order nonlinearity of a poled polymer film is erased by single pulse UV laser irradiation. In order to form the periodical structure in the optical polymer waveguide, the optical system of two-beam interference is arranged and a single pulse of UV laser is exposed directly onto the poled film. We prove that this method can simply fabricate thex(2)grating with the period from submicron to submillimeter.
