Abstract: Various embodiments of the present invention are directed to external, electronically controllable, negative index material-based modulators. In one aspect, an external modulator comprises a negative index material in electronic communication with an electronic signal source. The negative index material receives an electronic signal encoding data from the electronic signal source and an unmodulated carrier wave from an electromagnetic radiation source. Magnitude variations in the electronic signal produce corresponding effective refractive index changes in the negative index material encoding the data in the amplitude and/or phase of the carrier wave to produce an electromagnetic signal.

Abstract: A scattering spectroscopy apparatus, system and method employ guided mode resonance (GMR) and a GMR grating. The apparatus includes a GMR grating having a subwavelength grating, and an optical detector configured to receive a portion of a scattered signal produced by an interaction between an excitation signal and an analyte associated with a surface of the GMR grating. A propagation direction of the received portion of the scattered signal is substantially different from a propagation direction of a GMR-coupled portion of the excitation signal within the GMR grating. The system includes the apparatus and an optical source. The method includes exciting a GMR in a GMR grating, interacting a GMR-coupled portion of the excitation signal with an analyte to produce a scattered signal and detecting a portion of the scattered signal.
