The circuit shown in the figure measures relative humidity in air at the low temperatures found in applications like cold storage of food items and greenhouses. Instead of using electrical signal ...

Optical logic circuits employing microring resonators represent a rapidly evolving area within photonic integrated circuits, where miniaturised ring structures facilitate the realisation of high-speed ...

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 ...

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 ...

Using a relatively simplistic optical-interference technique, researchers are able to observe the motion of particles within a battery as it’s being charged and discharged. How optical interferometric ...

Quad-channel integrated circuits New Coherent quad-channel integrated circuits that enable faster, more efficient optical ...
