Polariton Filter Turns Ordinary Laser Light Into Quantum Light

An international team of researchers out of Macquarie University in Sydney, Australia, has demonstrated a new approach for converting ordinary laser light into genuine quantum light. Their approach uses nanometer-thick films made of gallium arsenide, which is a semiconductor material widely used in solar cells. They sandwich the thin films between two mirrors to manipulate ...
