Your library or personal account may give you access

Abstract

We implemented a high-resolution (0.1nm) on-chip spectrometer in C-band based on CMOS compatible silicon nitride microring array and convex optimized spectral reconstruction algorithm. The wide operation bandwidth and high precision make it promising in next generation optical communication network.
