(a) Scheme for polarized PL measurements. (b) Normalized I// as a function of polarizer angle: a single disk in red, and a single stacked-disk array in black. I// is the PL intensity measured at the direction parallel to the optical axis of the polarizer. The values of I// are normalized with their mean, and solid line is a cos2 fit. (c) PL images of SPs as a function of polarizer angle: a single disk (top) and a single stacked-disk array (bottom).
