Integrated scanning spectrometer with a tunable micro-ring resonator and an arrayed waveguide grating
文献摘要：
Integrated spectrometers with both wide optical bandwidths and high spectral resolutions are required in ap-plications such as spectral domain optical coherence tomography(SD-OCT).Here we propose a compact inte-grated scanning spectrometer by using a tunable micro-ring resonator(MRR)integrated with a single arrayed waveguide grating for operation in the 1265-1335-nm range.The spectral resolution of the spectrometer is de-termined by the quality factor of the MRR,and the optical bandwidth is defined by the free spectral range of the arrayed waveguide grating.The spectrometer is integrated with on-chip germanium photodetectors,which enable direct electrical readout.A 70-nm optical bandwidth and a 0.2-nm channel spacing enabled by scanning the MRR across one free spectral range are demonstrated,which offer a total of 350 wavelength channels with 31-kHz wavelength scanning speed.The integrated spectrometer is applied to measure different spectra and the interference signals from an SD-OCT system,which shows its great potential for future applications in sensing and imaging systems.
