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.
