An integrated high-resolution on-chip spectrometer is designed, fabricated and experimentally tested. A thermally tunable microring resonator is adopted to function as a tunable filter so as to retrieve the input spectrum. The robust integrated spectrometer is quite compact, low cost and CMOS-compatible. It has high potential to be used in on-chip sensing and spectroscopy systems.
