The Basics of Optical Wireless Power Transfer

Optical wireless power transfer involves the use of light to transmit energy from a source to a receiver without the need for physical connections like wires or cables.
This technology utilizes lasers or LEDs to convert electrical power into optical signals.
These optical signals are then directed towards a receiver equipped to convert the light back into electrical energy.

Key Components of the System

An optical wireless power transfer system typically consists of a transmitter, a medium, and a receiver.
The transmitter converts electrical energy into optical energy, usually through the use of a laser diode.
The medium through which the light travels could be air, optical fibers, or vacuum.
The receiver then converts the optical energy back into electrical energy, often using photodiodes.
