Science Daily  July 3, 2019 An international team of researchers (Singapore, Australia) has shown CMOS‐compatible, on‐chip Bragg solitons, with a soliton‐effect pulse compression with a factor of × 5.7, along with time‐resolved measurements of soliton fission on a CMOS‐compatible photonic circuit platform. These observations are enabled by the combination of a unique cladding‐modulated Bragg grating design and the high nonlinearity and negligible nonlinear loss of compositionally engineered ultra‐silicon‐rich nitride (USRN: Si7N3). Manipulating solitons on-chip could potentially allow for the speed up of photonic communications devices and infrastructure…read more. TECHNICAL ARTICLE
