Quantum Dots

Researchers at Linköping University created polarized light, which means all the light waves oscillate on the same plane. These polarized lights are used in LCD screens, energy-saving computer screens and wiretap-proof communications.  Polarized light was developed in a novel method by emitting photons from a quantum dot at the top of a micropyramid. This novel venture was published in the Nature periodical Light: Science & Applications. Semiconductive material gallium nitride was used in the micropyramid construction. This new method is a very promising technology for quantum encryption. It’s also proved theoretically that increased amount of indium in the quantum dots further improves the degree of polarization.
