Optical computing where circuits are replaced by light beams is a step closer with nanoantennaes that can be tuned to emit and receive particular wavelengths and manufactured without complex methods.

The authors of the article, published in Opto-Electronic Advances, propose an all-optical object identification and 3D reconstruction technique based on optical computing metasurface.

The idea of optical computing—the use of photons instead of electrons to perform computational operations—has been around for decades. However, interest has resurged in recent years; the ...

Optical computing and logic circuits represent a transformative approach to information processing, utilising light rather than electrons to execute computational tasks. This paradigm leverages ...

This work presents a new approach to designing Arithmetic Logic Units (ALUs) using electro-optic microring resonators. The methodology covers the demonstration of full and half addition and ...
