| 1 | Stimulated Brillouin scattering in chiral photonic crystal fiber显示文摘Stimulated Brillouin scattering(SBS)has many applications;for example,in sensing,microwave photonics,and signal processing.Here,we report the first experimental study of SBS in chiral photonic crystal fiber(PCF),which displays optical activity and robustly maintains circular polarization states against external perturbations.As a result,circularly polarized pump light is cleanly backscattered into a Stokes signal with the orthogonal circular polarization state,as is required by angular momentum conservation.By comparison,untwisted PCF generates a Stokes signal with an unpredictable polarization state,owing to its high sensitivity to external perturbations.We use chiral PCF to realize a circularly polarized continuous-wave Brillouin laser.The results pave the way for a new generation of stable circularly polarized SBS systems with applications in quantum manipulation,optical tweezers,optical gyroscopes,and fiber sensors. | Xinglin Zeng Wenbin He Michael HFrosz Andreas Geilen Paul Roth Gordon K.L.Wong Philip St.J.Russell Birgit Stiller | 2022 | Photonics Research2022，10，3： | 0 |
