Scientists demonstrate laser with controlled polarisation

Applied scientists at the Harvard School of Engineering and Applied Sciences (SEAS) in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, lasers in which the direction of oscillation of the emitted radiation, known as polarisation, can be designed and controlled at will. The innovation opens the door to a wide range of applications in photonics and communications. Harvard University has filed a broad patent on the invention...
