Dispersion Compensating Silicon Nitride Waveguide Bragg Gratings for Ultrashort Pulse Compression
We demonstrate post-compression of ultrashort pulses from 170 to 62 fs using chirped Bragg gratings in a silicon nitride-on-insulator platform with 164 nm reflection bandwidth. To our knowledge, this represents a record large reflection bandwidth and the first sub-100 fs ultrashort pulses generated using apodizing chirped Bragg gratings on a silicon chip.
