An array of dielectric resonators is formed on a substrate. Each resonator includes an active medium having an optical transition that is operative in a process of photodetection or photoemission. The active media each include a quantum well multilayer. The dielectric resonators in the array are each dimensioned to provide a resonance that lies substantially at the frequency of the optical transition.

Active optical device enabled by dielectric metamaterials

An array of dielectric resonators is formed on the substrate of an optoelectronic device. Each resonator includes an active medium having an optical transition that is operative in a process of photodetection or photoemission. The dielectric resonators in the array are each dimensioned to provide a resonance that lies substantially at the frequency of the optical transition.

Optoelectronic apparatus enabled by dielectric metamaterials

A method of nonlinear wavelength generation uses a nonlinear optical medium. An input flux of pump energy is applied to one or more dielectric optical resonators. Each resonator has an optical cavity comprising the nonlinear optical medium. Each resonator has at least one Mie resonance that is excited by the input flux of pump energy. The pump energy causes the generation of converted light containing at least one converted component having a frequency attainable only through a non-linear process.

Nonlinear optical frequency conversion using metamaterial arrays

A new monolithic resonator metasurface design achieves ultra-high Q-factors while using only one resonator per unit cell. The metasurface relies on breaking the symmetry of otherwise highly symmetric resonators to induce intra-resonator mixing of bright and dark modes (rather than inter-resonator couplings), and is scalable from the near-infrared to radio frequencies and can be easily implemented in dielectric materials. The resulting high-quality-factor Fano metasurface can be used in many sensing, spectral filtering, and modulation applications.
