1Chip-scale full-Stokes spectropolarimeter in silicon photonic circuits显示文摘Wavelength dependent polarization state of light carries crucial information about light-matter interactions.However,its measurement is limited to bulky,high energy-consuming devices,which prohibits many modern,portable applications.Here,we propose and demonstrate a chip-scale spectropolarimeter implemented using a complementary metal oxide semiconductor compatible silicon photonics technology.Four compact Vernier microresonator spectrometers are monolithically integrated with a broadband polarimeter consisting of a 2D nanophotonic antenna and a polarimetric circuit to achieve full-Stokes spectropolarimetric analysis.The proposed device offers a solid-state spectropolarimetry solution with a small footprint of 1 mm × 0.6 mm and low power consumption of 360 mW.Full-Stokes spectral detection across a broad spectral range of 50 nm with a resolution of 1 nm is demonstrated in characterizing a material possessing structural chirality.The proposed device may enable a broader application of spectropolarimetry in the fields ranging from biomedical diagnostics and chemical analysis to observational astronomy.ZHONGJIN LIN TIGRAN DADALYAN SIMON BELANGER-DE VILLERS TIGRAN GALSTIAN WEI SHI 2020Photonics Research2020,8,6:1
