Indium Tin Oxide Might Be the Material Photonics Has Been Waiting For

There are plenty of reasons why it’s useful to transfer information through photons or use light particles to carry out tasks within a system or device, speed chief among them. But in order to use photons with even greater dexterity in the future, researchers will need to control the way light behaves as it passes through a material. One way to do this is by adjusting the material’s refractive index to cause light to travel faster or slower through it. This is a particularly good option for materials that naturally alter their refractive index according to the intensity of light to which they are exposed. Such materials behave differently depending on whether the light passing through comes from a low-power source or a high-powered laser. These materials are known as optically nonlinear. In the world of photonics, having a higher degree of optical nonlinearity is considere...
