The focus of this paper is the characterization of electro-optic properties of single crystal thin films of organic material NPP grown by the plate-guided method. Characterization was performed using the longitudinal a.c. modulation technique. Half-wave voltage Vπ, figure-of-merit F, and electro-optic coefficient r63 were estimated to be 3.24 kV, 0.98×10-10 m/V and 25.8×10-12 m/V respectively. We found that crystalline z-axis is off the normal to the plane of the film at an angle of 70. We also proposed a transverse version of a thin film electro-optic modulator with low driving voltage, which is based on a single-arm thin film waveguide interferometer.
