Abstract :
We demonstrate a three-stage double channel cascaded microrings integrated with grating couplers based on SOI rib waveguide. The resonant frequencies were well matched at the drop-port and still splitting at the through-port which was considered to be due to fabrication variations. Flat-top and broadened bandwidth were achieved in the three-stage microring device.
