Photonic crystal cavities and related devices and methods

摘要

Photonic crystal cavities and related devices and methods are described. The described cavities can be used as lasers, photovoltaic sources, and single photon sources. The cavities can be both optically and electrically pumped. A fabrication process of the cavities is also described.

1. An optically-pumped photonic crystal laser comprising:
a pump laser; and a photonic crystal cavity comprising:
i) a photonic crystal slab comprising a plurality of air-holes arranged periodically, a defect region, and a gain medium; andii) a metal cladding underlying the photonic crystal slab,wherein, in an operative condition, the pump laser emits light onto the defect region of the photonic crystal cavity to create carriers confined in the gain medium to generate light, the light being emitted in a non-parallel direction with respect to a plane corresponding to a planar interface between the metal cladding and the photonic crystal slab, and wherein the metal cladding comprises a metal that is over 98% reflective to a wavelength of the emitted light.
