(a) The scheme to generate coupling and probe lights. DL100, diode laser; ISO, optical isolator; PBS, polarizing beam splitter; AOM, acousto–optic modulator. (b) The scheme of the experiment. The coupling and probe lights are converted into right-handed and left-handed circularly polarized lights, respectively, by two GlanTaylor polarizer (GT) and quarter-wave plates. A pinhole is used to reduce the diameter of the probe light. PD, photodiode.
