Laser Polarization Controlled
CAMBRIDGE, Mass., April 13, 2009 -- Lasers with controlled polarization were demonstrated for the first time through the integration of the polarizer on the laser facet, an innovation that could open new applications in photonics and communications. Harvard Univerity and Hamamatsu Photonics researchers showed that the direction of oscillation of the emitted radiation, known as polarization, can be designed and controlled at will. "Polarization is one of the key features defining a laser beam. Controlling it represents an...
