Researchers demonstrate a platform for future optical transistors

EurekAlert  April 9, 2020 The inability of photons to interact well with each other is a drawback in developing optical transistors. An international team of researchers (Russia, Iceland, UK) demonstrated a new efficient implementation, where photons couple to excitons in single-layer semiconductors. They created polaritons with the help of a laser, a waveguide, and an extremely thin molybdenum diselenide semiconductor layer trapping them in the system. Polaritons obtained in this way not only exist for relatively long periods of time, but also have extra high nonlinearity, meaning that they actively interact with each other. The work brings us closer to […]
