%X 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~10 6. Numerical calculations indicate a large number of high- Q modes with high sensitivity, which are ideal for simultaneous, multi-parameter refractive index-based sensing.
