Photonic crystal (PhC) nanocavities with ultrahigh Q values are reviewed. The demonstrated Q for a width-modulated PhC nanocavity is extremely high at 1.2×10⁶, which corresponds to a photon lifetime of ~1 ns. In addition, an ultrahigh Q of 3.2×10⁵ is demonstrated using a point defect type hexapole cavity. The extremely long photon lifetime enables us to fabricate devices, such as photonic DRAMs, chip integrated slow light materials, and novel wavelength converters.
