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 ...

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 ...

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 ...

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 ...

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

Researchers have shown that single photons can be emitted in a uniform way from quantum dots arranged in a precise pattern. The team has used such methods to create single-quantum dots, with their ...

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 ...

The reflex, or “red-dot,” sight is a popular category of optical aiming/pointing aids, which finds diverse applications in astronomy, archery, shooting, etc. In the reflex-style sight, a source ...
