|Abstract: ||A photonic apparatus includes a metamaterial resonator array overlying
and electromagnetically coupled to a vertically stacked plurality of
quantum wells defined in a semiconductor body. An arrangement of
electrical contact layers is provided for facilitating the application of
a bias voltage across the quantum well stack. Those portions of the
semiconductor body that lie between the electrical contact layers are
conformed to provide an electrically conductive path between the contact
layers and through the quantum well stack.
