System to control optical signals with optical signals

Applications: Computing, routing, signal processing

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

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.
