Described herein are embodiments of transmitting power wirelessly that include driving a high-Q non-radiative resonator at a value near its resonant frequency to produce a magnetic field output, said non-radiative-resonator formed of a combination of resonant parts, including at least an inductive part formed by a wire loop, and a capacitor part that is separate from a material forming the inductive part, and maintaining at least one characteristic of said resonator such that its usable range has a usable distance over which power can be received, which-distance is set by a detuning effect when a-second resonator gets too close to said resonator.

A waveguide structure is provided. The waveguide structure includes a photonic crystal structure comprising gyromagnetic materials arranged in a two-dimensional lattice formation that exhibits a plurality of one-way modes produced as a result of magneto-optic effects. One or more confining barriers are positioned around the photonic crystal structure so as to allow the one-way modes to propagate through the photonic crystal structure. One or more radiation sources are positioned in or around the photonic crystal structure so as to couple electromagnetic energy into and out of the waveguide. One or more static external magnetic field sources induce the magneto-optic effects such that the one-way modes are allowed to propagate in one direction in the photonic crystal structure.

The invention provides an optical fiber photodetector including a photoconductive element, such as a semiconducting element, having a fiber length. The semiconducting element is characterized as a non-composite material in at least one fiber direction. At least one pair of conducting electrodes is in contact with the semiconducting element along the fiber length, and an insulator is provided along the fiber length. An optical resonator can be disposed along the fiber length and along a path of illumination to the semiconducting element. The resonator is dimensioned to substantially reflect all illumination wavelengths except for a prescribed range of wavelengths transmitted to the semiconducting element. The fiber photodetector can be arranged in a photodetecting fiber grid, photodetecting fiber fabric, or other configuration for detecting incident illumination.
