Photonic Devices

Enhancement and localization provided by optical nanocavities offer a perfect platform to build on-chip components such as sources, modulators, routers and detectors for integrated optoexcitonic circuits. Nanocavities can assist in satisfying the projected on-chip interconnect power budget by enabling efficient low energy photon sources. For example, high quality factor/mode volume (Q/V) nanocavities such as those formed using photonic crystals can dramatically reduce laser thresholds. Nanocavities can also be used to change the local optical density of states for directed spontaneous emission or for achieving coherent spontaneous emission (polariton laser).
