Fig. 6.
(a) Relative frequency shifts of 214 μm long and 61 μm thick SiN strings of varying widths and (b) relative frequency shifts of 5.5 μm wide and 185 nm thick SRN strings of different lengths. For all measurements, the readout laser was positioned at the center of the string with the laser power changed instantly from 2 to 200 μW. The error bars represent standard deviations, and the red lines are linear fits of the data points.
