Reconfigurable, Defect-Free, Ultrahigh-Q Photonic Crystal Microcavities for Sensing

We propose a new approach for creating reconfigurable high-Q cavities in defect-free photonic crystal slabs (PCSs). The approach relies on selective air-hole infiltration in otherwise defect-free PCSs. We show that using this method we can design ultrahigh-Q microcavities, with Q~106. Numerical calc...
