AbstractMeasurements of the electro-optic coefficient, r33, of a zwitterionic organic chromophore are reported. Amorphous polycarbonate and chromophore were mixed and spin-processed to obtain host-guest polymer thin films for measurement with a Teng-Man modulation eillipsometer. After poling, the films exhibited an r33 of 100 pm/V at a measurement wavelength of 1310 nm, around three times greater than that of crystalline LiNbO3. Given this chromophore's high figure of merit a high r33 is expected, although the electro-optic response in the poled polymer films decayed rapidly over several days. © 2009 American Institute of Physics.
