Researchers at the Singapore University of Technology and Design (SUTD), the A*STAR Institute of Microelectronics, and MIT have developed an all-optical spectrotemporal pulse compression system. The system, which is built on a CMOS-compatible ultra-silicon-rich nitride (USRN) platform, is based on an integrated design that provides direct, tailored control of a pulse’s spectral and temporal profiles. The ability to control pulse properties will allow users to efficiently leverage them for advanced metrology, high-speed optical communications, and more.
To achieve a strong rate of compression at low power, the researchers designed a device with separate nonlinear and dispersive stages integrated on one chip. Decoupling these…READ MORE
