Such gratings exhibit narrow reflection bandwidth and highly tailorable resonant wavelengths, allowing versatile functionalities in nonlinear integrated circuits.This work has been made possible through access to the OptoFab node of the Australian National Fabrication Facility (ANFF-OptoFab). The authors also acknowledge Ziqian Zhang for providing insights into figure-making.application/pdfen-AU© CLEO 2023 © Optica Publishing Group 202320232024-04-28
