(a) Experimental setup to measure the power scaling of the Q factor, Q/Q0. (b) Example probe transmission scans for a-Si:H ring B, for various coupled pump powers. (c) Q/Q0 for the a-Si:H devices, fit to equation 11, error bars are determined by averaging over several data sets. The subplot shows the extrapolated fits for Q/Q0 compared to a model for an equivalent c-Si micro-ring, based on equation 10. The region of the main plot is indicated by the shaded area in the sub-plot.
