NANOWIRE PHOTONIC CIRCUITS, COMPONENTS THEREOF, AND RELATED METHODS

摘要

The present invention generally relates to energy transmission in materials, specifically, electromagnetic (e.g., photonic) pathways and circuits, including various components for use in such pathways and circuits, for example, nanoscale wires such as semiconductor nanowires. One aspect of the invention is the propagation of energy in the form of electromagnetic radiation in a material such as a nanoscale wire (20) at or near the band edge (i.e., at or near the band gap wavelength), of the material, as defined below, optionally along with energy propagation at one or more different energy levels. Such propagation allows for a variety of new arrangements and methods, including diodes and other devices, transmission of electromagnetic radiation around tight corners with low loss, coupling between materials, electric field-generated generation of amplitude-varying electromagnetic radiation, and other features.
