A team of computer and electrical engineers at the University of California, Santa Barbara, working with several colleagues from California Institute of Technology and another pair from Anello Photonics has developed a first-of-its-kind chip that hosts both a laser and a photonic wave guide. In their paper published in the journal Nature, the group describes how they made the chip and how well it worked when tested.
