| 1 | Long-range optical trapping and binding of microparticles in hollow-core photonic crystal fibre显示文摘Optically levitated micro-and nanoparticles offer an ideal playground for investigating photon–phonon interactions over macroscopic distances.Here we report the observation of long-range optical binding of multiple levitated microparticles,mediated by intermodal scattering and interference inside the evacuated core of a hollow-core photonic crystal fibre(HC-PCF).Three polystyrene particles with a diameter of 1μm are stably bound together with an inter-particle distance of~40μm,or 50 times longer than the wavelength of the trapping laser.The levitated boundparticle array can be translated to-and-fro over centimetre distances along the fibre.When evacuated to a gas pressure of 6 mbar,the collective mechanical modes of the bound-particle array are able to be observed.The measured interparticle distance at equilibrium and mechanical eigenfrequencies are supported by a novel analytical formalism modelling the dynamics of the binding process.The HC-PCF system offers a unique platform for investigating the rich optomechanical dynamics of arrays of levitated particles in a well-isolated and protected environment. | Dmitry S.Bykov Shangran Xie Richard Zeltner Andrey Machnev Gordon K.L.Wong Tijmen G.Euser Philip St.J.Russell | 2018 | Light(Science & Applications)2018，7，1： | 3 |
| 2 | 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 |
