- Left and right circularly polarized light, where the electromagnetic waves spiral in a clockwise and counterclockwise manner as they travel, plays a crucial role in a wide range of applications, from enhancing medical imaging techniques to enabling advanced communication technologies. However, generating circularly polarized light often requires complex and bulky optical set-ups, which hinders its […]
- The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at present. These optical clocks are still being assessed, but already now, some are 100 times more accurate than cesium clocks. They will […]
