On-demand control of terahertz and infrared waves

The ability to control infrared and terahertz waves using magnetic or electric fields is one of the great challenges in physics that could revolutionise opto-electronics, telecommunications and medical diagnostics. A theory ...

Confined nanoscale sound controls light in a microresonator

When traversing a solid material such as glass, a light wave can deposit part of its energy in a mechanical wave, leading to a color change of the light. This process, called "Brillouin scattering," has important technical ...
