Bragg Soliton Fission: Bragg Soliton Compression and Fission on CMOS‐Compatible Ultra‐Silicon‐Rich Nitride (Laser Photonics Rev. 13(8)/2019)

In article number 1900114, Ezgi Sahin, Dawn T. H. Tan, Benjamin J. Eggleton, and co‐workers describe how optical pulses propagating through a nonlinear ultra‐silicon‐rich nitride (USRN) grating experience high anomalous group‐velocity dispersion at the photonic band edge. The grating‐induced dispersion counteracts the large optical nonlinearity and Bragg solitons form. At different power regimes, the Bragg solitons experience temporal compression of varying degrees. Third‐order dispersion initiates Bragg soliton fission. Temporal dynamics of Bragg soliton‐effect compression and fission are experimentally observed.
