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 ...

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 ...

With the exponential growth of data globally, the demand for high-speed acquisition and long-distance transmission of multidimensional data is escalating. Online video surveillance in sectors like ...

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 ...

Tiny circuits can go the distance. Researchers have mapped a noise-reducing magneto-optical response that occurs in fiber-optic communications, opening the door for new materials technologies. Optical ...

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

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 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 ...
