Single-crystal films of 2-cyclooctylamino-5-nitropyridine have been prepared by the shear method, and the second-order susceptibility has been measured by second-harmonic generation. Polarization-dependent measurements in an a plate show that the maximum value of deff (~56 pm/V) is approximately 10 times larger than that of LiNbO3 and that the ratio d32/d33 is approximately −4 at a 1064-nm wavelength. This material has a phase-matching direction (type I only) for propagation parallel to the plane of the a plate. The results of these measurements are important for phase-matched second-harmonic generation in waveguides of this material.
