In this work, we employ 87Rb atoms as rotation media to manipulate the polarization of optical fields in both magnetic and magnetic -free environments. Employing the nonlinear magneto -optical rotation mechanism, we achieve a state-of-the-art magneto -optical rotation coefficient of 1.74 x 108 rad center dot T-1 center dot m-1 which is four orders of magnitude higher than commonly employed materials. Additionally, in a magnetic -free environment, we achieve all -optical cross -polarization modulation between the pump and probe light via Rb atoms. The nonlinear magneto -optical rotation configuration introduces inventive techniques for a new type of magnetooptical modulator while the all -optical configuration paves the way for exploring photonic integrated circuit (PIC) devices free from disruptions caused by electrical or magnetic crosstalk.
