Researchers at the University of Michigan have developed a more efficient way to produce coherent laser-like beams that use 250 times less power than conventional lasers. The team believes they have created the first polariton laser to run on electrical current and work at room temperature.
To develop this new laser, the team created a design that involved moving mirrors from the top and bottom of the device to the sides and kept the electrodes on the top and bottom. This allowed the team to create the beam of light with an electrical signal and create an environment that encouraged polaritons to form and emit light.
