The oscillators have M=0, 1 or 2 resonant dimensions on a micro-scale (approximately 1 um to approximately 1 mm) to emit radiation having a local peak at a desired wavelength in the IR or THz regions. The oscillators have at least one non-resonant dimension on a nano-scale (less than approximately 100 nm) to suppress vibration modes in that dimension and channel more thermal energy into the local peak. The photonic crystal defect cavities have N=1, 2 or 3 (N>M) resonant dimensions on the microscale with lengths comparable to the length of the oscillator and the desired wavelength to exhibit a cavity resonant that overlaps the local peak to accept and transmit emitted radiation. The energy from multiple oscillator/defect cavities pairs can be collected and transmitted by an internal waveguide or external mirrors and lens to a specified location where it is output. To improve coupling efficiency, the oscillators and defect cavities preferably exhibit a physical symmetry so that they are substantially “mode matched”. The integration of nano-scale emitters with micro-scale photonic crystal defect cavities creates a new class of metamaterials that more efficient generate radiation. | 05-06-2010 |
