ABSTRACT:
A negative refractive index device and a method of generating radiation. In one embodiment, the device includes: (1) an optical input configured to receive light and (2) an optical medium having a negative index of refraction and a second-order nonlinearity proximate a center frequency of the light, coupled to the optical input and configured to resonate in response to the light to yield radiation having a phase velocity based on a group velocity of the light.
