German-Indian research team achieves further step towards miniaturised optical isolators / For on-chip integration of optical computer technologies It has been known for centuries that light exhibits ...
It has been known for centuries that light exhibits wave-like behaviour in certain situations. Some materials are able to rotate the polarisation, i.e. the direction of oscillation, of the light wave ...
Physicists have shown that ultra-thin two-dimensional materials such as tungsten diselenide can rotate the polarization of visible light by several degrees at certain wavelengths under small magnetic ...
