The goal of this project is to create a wireless optical communication system that operates at high frequencies (up to 3 GHz). The system will function by taking a digital electric input signal, converting it to a photonic signal, recovering the signal at the other end of a short distance (~1 foot) and converting it back into a digital signal. Unlike the more common fiber-optic data transmission systems, this system will transmit light through air, instead of fiber, as its medium. Doing so will have the benefits of a wireless system combined with the benefits from an optical system, including voltage isolation, no interference from electromagnetic waves, and no cross talk from other electrical signals.
Research for this project will consist of how to optimize an optical isolator system for high frequencies. This includes determining optimal wavelength of the light to be transmitted, the power necessary to successfully transmit the signal, and LED’s and photo-detectors that are well suited for these requirements. Also, since these systems are useful in industry, cost of materials and production are important factors, and will be taken into consideration when selecting components.
