System to control optical signals with optical signals

The invention solves a huge challenge in photonics – how do you control one wavelength of light with another.

Applications: Computing, routing, signal processing

Features	Benefits
Direct control of one optical signal using another optical signal at different wavelength	Reduced overall device footprint and energy consumption; Opens the possibility of fully optical processing; Highly scalable with intrinsically high bandwidth
Standing waves are formed of either or both a controlled signal and the control signal	Creates a spatially well-defined distribution of the optical field which can be controlled for high precision and strong interactions between signals
Antenna formed of absorbing functional materials	Allows for wavelength-selective lossless modulation
