Tunable Bragg Gratings in Polymer Thin Films

Abstract:

Bragg gratings were inscribed in poled host-guest polymer thin films containing anelectro-optically active chromophore. Probing the grating in reflection, with a transparent con-ducting electrode on one side of the film and a gold-coated electrode on the other, a modulatingelectric field was observed to induce a modulation in the grating efficiency consistent with thatexpected from the measured electro-optic coefficient.
