We report optical second harmonic generation measurements in single crystal α-SiC of polytype 6H. The sample was found to be optically uniaxial, consistent with the hexagonal symmetry of the crystal structure. The two independent components of the second order electric susceptibility tensor were determined to be d33 = 43 pm/V and d 31 = -4.3 pm/V. From this data the principle electro-optic coefficient was computed to be r33 = 100 pm/V. The corresponding figures of merit for nonlinear optical device operation compare favorably with leading materials such as lithium niobate and KTP, and thus the relatively convenient and inexpensive fabrication of 6H SiC thin films could prove useful for integrated optical devices.
