Abstract

We propose and demonstrate a cascaded micro-ring structure based on silicon nitride to achieve on-chip signal detection and spectral reconstruction. The core of the system is eight rings with different radii. We have developed a mathematical algorithm based on convex optimization theory to achieve spectral reconstruction with a resolution of 0.08 nm and a bandwidth of 40 nm.
