Figure 6

Dynamic control of transverse shift.

For a normally incident light in cross polarizer/analyzer setup optical spin Hall transverse shift is dynamically controlled. (a) Saw-tooth waveform of LCVR driving voltage is plotted. (b) Retardance of LCVR and (c) SUM and Y of PSD are plotted as a function of LCVR driving voltage. Oscilloscope traces of (d) saw-tooth waveform and SUM of PSD and (e) SUM and Y of PSD are shown. (f) Switching between positive and negative Y is demonstrated as driving voltage is varied.
