(a) Experimental setup to measure the angular response of the polymer microring, experimental data (dot) and theoretical calculation (line) of angular response of the polymer microrings with D=60 μm at 20 MHz (solid dot and line) and 30 MHz (empty dot and dashed line) (b), and with D=40 μm at 30 MHz (solid dot and line) and 40 MHz (empty dot and dashed line) (c).
