Abstract
Integrated Bragg gratings leverage a periodic effective index modulation of a guided wave medium. Highly nonlinear Bragg gratings may leverage the large dispersion on the edge of or within the grating stopband to generate a multitude of nonlinear dynamics. Bragg solitons are described by soliton solutions from the nonlinear coupled mode equations in one dimensional periodic structures. These Bragg soliton solutions which reside within the grating stopband are a specific class referred to as gap solitons. We have realized high quality Bragg gratings implemented on the ultra-silicon-rich nitride platform for observations of Bragg soliton dynamics. We discuss experimental observations of Bragg soliton-effect temporal compression, fission, thermo-optically tuned spectral broadening, optical parametric Bragg amplification, picosecond pulse generation and pure quartic Bragg solitons.
