Sensors employing nanoparticles and microcavities

A method and apparatus for enhanced optical emissions, the apparatus comprising a light source, a microcavity, and a medium comprising nanoparticles, located within or near the microcavity. The nanoparticles are either non-aggregated or are aggregated in the form of fractals. The nanoparticles and microcavity exhibit enhanced linear and non-linear optical emission. The light emitting apparatus can be used for wavelength translation, amplification, optical parametric oscillation, light detection and ranging, increased sensitivity, high density optical data storage, and near-field optical spectroscopy.
