Cornell professor Michal Lipson heads a research group of a dozen EEs pursuing nanoscale photonics. The team has created silicon photonic chips that confine light in very small cavities that can slow ...

Let’s think of the last time you sent data without wires. We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to transmit ...

Optical waveguides are structures that guide and confine light within a small cross-sectional area. In nanophotonic circuits, waveguides are typically fabricated using high-refractive-index materials ...

Photonic circuits, which manipulate light to perform various computational tasks, have become essential tools for a range of advanced technologies—from quantum simulations to artificial intelligence.

The field of all‐optical logic circuits has garnered significant attention in recent years, particularly with the integration of micro‐ring resonators to process information entirely via light. These ...

A further benefit is that the channels can be multiplexed, allowing many quantum processors to access the system at the same ...

Scientists have developed an ingenious method to create and control ultra-confined light waves, a significant step towards realizing tiny optical circuits. This method works in two steps, like giving ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers. If you are reading this on your smartphone, its CPU (central processing ...

Researchers are working hard around the world to try and improve the speed available for data sharing. Microsoft Research and EPFL recently demonstrated ultrafast optical switching utilizing a ...

Researchers from the University of Southampton (UK), and the Institut d'Optique in Bordeaux (France) have devised a new approach for controlling light in a silicon chip by bringing the concept of ...

Optical illusions come in all forms, from mind-bending physiological phenomena to confusing cognitive images, but one variety that doesn't get nearly enough love is the humble ambigram. While these ...
