  We outline the design for a photonic crystal resonator made in a hybrid
Silicon/Lithium Niobate material system. Using the index contrast between
silicon and lithium niobate, it is possible to guide and confine photonic
resonances in a thin film of silicon bonded on top of lithium niobate. Quality
factors greater than $10^6$ at optical wavelength scale mode volumes are
achievable. We show that patterning electrodes on such a system can yield an
electro-optic coupling rate of 0.6 GHz/V (4 pm/V).
