| 1 | Tunable optical spin Hall effect in a liquid crystal microcavity显示文摘The spin Hall effect,a key enabler in the field of spintronics,underlies the capability to control spin currents over macroscopic distances.The effect was initially predicted by D'Yakonov and Perel1 and has been recently brought to the foreground by its realization in paramagnetic metals by Hirsch2 and in semiconductors3 by Sih et al.Whereas the rapid dephasing of electrons poses severe limitations to the manipulation of macroscopic spin currents,the concept of replacing fermionic charges with neutral bosons such as photons in stratified media has brought some tangible advances in terms of comparatively lossless propagation and ease of detection4–7.These advances have led to several manifestations of the spin Hall effect with light,ranging from semiconductor microcavities8,9 to metasurfaces10.To date the observations have been limited to built-in effective magnetic fields that underpin the formation of spatial spin currents.Here we demonstrate external control of spin currents by modulating the splitting between transverse electric and magnetic fields in liquid crystals integrated in microcavities. | Katarzyna Lekenta Mateusz Król Rafał Mirek KarolinaŁempicka Daniel Stephan Rafał Mazur Przemysław Morawiak Przemysław Kula Wiktor Piecek Pavlos G.Lagoudakis Barbara Piętka Jacek Szczytko | 2018 | Light(Science & Applications)2018，7，1： | 1 |
| 2 | Charge distribution into illuminated dye-doped surface stabilized ferroelectric liquid crystal cell显示文摘Surface stabilized(anti)ferroelectric liquid crystal cells can be used as an optically addressed media for optical data processing.The structure of the cell has to contain a photo sensible agent,i.e.,an absorbing dye-doped orienting layer.The all-optical generation of the diffractive grating can be done due to the switching parameters of the smectic slab within cells with a sensitive layer.This Letter considers a study of the optically induced charge generation into the dye-doped layer,and the explanation of the phenomena of the selective molecular director reorientation,while cell driving what leads to the induction of phase grating. | Marek Sutkowski Wiktor Piecek | 2016 | Chinese Optics Letters2016，14，10： | 0 |
