Widely Tunable, High-Q Two-Dimensional Photonic Crystal Cavities for cQED Applications

A fractured planar photonic crystal cavity is designed so that its resonant frequency can be mechanically tuned over a range of tens of nanometers while maintaining a quality factor in excess of 100,000. Experimental data validates the tuning capability, in lower Q cavities.
