The bandwidth is observed to decrease as temperature increases, corresponding to a red-shift in the high dispersion region of the Bragg grating.Engineering, Electrical & ElectronicOpticsPhysics, AppliedEngineeringPhysicsThermo-optic tuning of spectral broadening in a nonlinear Ultra-Silicon-Rich Nitride gratingtext::conference output::conference proceedings::conference paper
