An Integrated Large Dispersion Optical Delay Line Based on Cladding-modulated Chirped Grating
We demonstrate an on-chip circulator-free narrow-bandwidth, large-dispersion delay line based on 20.11-cm-long Archimedean spiral cladding-modulated chirped Bragg gratings on a silicon nitride platform. The device achieves a 558-ps/nm dispersion over a bandwidth of 2.8 nm.
