Universal Optical Traffic Controllers for Smaller and More Efficient Photonic Chips

digitalPrototypeTRL 3

Imagine a one-way street for light on a computer chip that prevents signals from crashing into each other. Current versions are bulky and hard to fit, but this project uses a special 'magnetic paint' and tiny gold structures to make them shrink. This allows different light-based components to be packed tightly together on any type of chip material.

The business problem

What needed solving

Current photonic chips lack a small, integrated way to route light in one direction (circulators), forcing manufacturers to use bulky external components that increase power use and size.

The solution

What was built

A method to deposit magneto-optical sol-gel materials onto any chip and a proof-of-concept for a three-port optical circulator.
