A simple model system to study coupled photonic crystal microcavities

Mid-infrared silicon-on-sapphire waveguide coupled photonic crystal microcavities

Optically tunable silicon photonic crystal microcavities.

We demonstrate the use of silicon photonic crystal based microcavity structures to perform light modulation at potentially giga-Hertz speeds through the use of optically induced plasma dispersion. The cavity configurations considered have the potential to operate at low pump power when the Q of the cavity involved is maximized.

Magnetic imaging in photonic crystal microcavities.

We demonstrate the nonresonant magnetic interaction at optical frequencies between a photonic crystal microcavity and a metallized near-field microscopy probe. This interaction can be used to map and control the magnetic component of the microcavity modes. The metal coated tip acts as a microscopic conductive ring, which induces a magnetic response opposite to the inducing magnetic field. The r...

Optical fiber coupling to planar photonic crystal microcavities

Recently it has been demonstrated that resonant microcavities formed in planar photonic crystals (PC) are capable of not only confining light to ultra-small optical mode volumes[1], but can also be made of high enough quality to enable photon cavity lifetimes capable of, for instance, reaching strong-coupling with atomic Cs[2] or semiconductor quantum dots[1, 3, 4]. In many of the proposed appl...
