Research output: Contribution to journalConference articlepeer-review


A simple fabrication technique of nonlinear polymeric optical waveguide patterns was introduced. It is found that the second-order nonlinearity of a poled polymer film is erased by visible laser irradiation. A high resolution χ(2) grating was realized based-on laser-beam direct writing technique.
