Abstract:

A microring resonator (MRR) cavity-enhanced on-chip Fourier-transform spectrometer (FTS) is demonstrated. High resolution (1.7 nm) and large bandwidth (at least 100 nm) are achieved with the help of high-Q cavity. The on-chip spectrometer is very robust, cheap and compatible with other integrated photonic devices. It is promising to be applied in integrated photonic sensing and on-chip spectroscopy system.
