Physicists have developed the smallest electrically pumped laser ever, with a beam that is 30 micrometers long, eight micrometers high, and has a wavelength of 200 micrometers. It is the first time that a laser has been created that is smaller than the wavelength its light emits. Scientists think this product could one day change the way that computer chips are made. “If we manage to approximate the transistors in terms of size using the microlasers, one day they could be used to build electro-optic chips with an extremely high concentration of electronic and optic components,” said Christoph Walther, a PhD student in the Quantum Optoelectronics Group at ETH Zurich
