1. A nanobeam cavity device comprising:
an elongated waveguide having a central optical cavity, the waveguide being suspended in air such that air surrounds a top, a bottom, and opposed lateral sides of the waveguide;
first and second lateral substrates that are positioned on opposed lateral sides of the waveguide; and
carrier-injection beams that extend from the first and second lateral substrates to the central optical cavity of the elongated waveguide.
