In certain examples, methods and semiconductor structures are directed to an apparatus including source circuitry configured to provide power to other circuitry, with the source circuitry including amplification circuitry (e.g., with a power-switching output) and a source resonator. The amplification circuitry is to provide power to the source resonator with a gain that is dependent on a coupling rate between the source circuitry and other external-receiving circuitry. The source circuitry is also to offset phase delay caused by the amplifier. In operation, the source resonator generates a magnetic field in response to the power, for highly-efficient wirelessly transfer of the power to the other circuitry.

Systems and methods involving wireless power transfer using an amplifier with gain and feedback

In certain examples, methods and semiconductor structures are directed to an apparatus including a photon emitter such as an LED which operates over an emission wavelength range and a photo-voltaic device arranged relative to the photon emitter to provide index-matched optical coupling between the photo-voltaic device and the photon emitter for an emission wavelength range of the photon emitter.

Apparatuses and methods involving DC voltage conversion using photonic transformers

Various embodiments are directed to apparatuses and methods related to source circuitry that provide power to other circuitry. The source circuitry including gain circuitry and a source resonator. The gain circuitry provide powers to the source resonator with a gain that is dependent on a coupling rate between the source circuitry and other circuitry. The source resonator is coupled to the gain circuitry and generates a magnetic field in response to the power. The source circuitry is configured and arranged to wirelessly transfer the power to the other circuitry via the magnetic field.
