摘要： An active chiral photonic metamaterial having a dynamically controllable photonic material parameter is employed in a system and a method of polarization rotation. The active chiral photonic metamaterial includes a first chiral photonic element formed in a first metal layer, a second chiral photonic element formed in a second metal layer, and an active material layer disposed between the first and second metal layers. The active material layer includes the photonic material parameter that is dynamically controllable. A coupling between the first chiral photonic element and the second chiral photonic element is a function of the photonic material parameter of the active material layer. The system further includes a means for controlling the dynamically controllable photonic material parameter. The method includes illuminating the active chiral photonic metamaterial with an optical signal and applying a control signal to vary the dynamically controllable photonic material parameter.

摘要： 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.
