Althoughthere are many ways to implement an integrated opticalbuffer, such as the use of ring resonators, photonic crystals,Bragg gratings and spiral waveguides, it is still challenging torealize optical buffers with long storage time and low loss.Photonic integrated circuits with small size are of interest forimplementing optical buffers. In general, three materials systemsare employed to implement integrated optical buffers, silicon,silicon nitride and indium phosphide. However, it is hardto implement optical buffers with a storage time over tens ofnanoseconds due to the intrinsic high loss of these materials.展开更多
