In situ measurement in which a quarter-wave plate is rotated during device operation, showing the increase and decrease with selectivity for right-handed (RH) and left-handed (LH) circular polarization. Scan number corresponds to increasing time. Decrease in overall luminescence is presumed to be because of Joule heating.
