We propose two novel concepts for creating high-Q cavities in photonic crystal slabs (PCS). We show that photonic crystal slab-based double-heterostructure cavities, formed by variations in the refractive index of photosensitive PCS or formed by air-hole infiltration, can have large Q-factors (Q > 1 × 106). ©2007 IEEE.
