Hristu, S. Stanciu, S. Wu, F.-J. Kao, O'D. Kwon, G. Stanciu] A confocal laser scanning microscope modified to acquire optical beam induced current images is used to investigate a novel type of semiconductor lasers—photonic quantum ring lasers. We compare the lasing and the photoinduced current images of the structures and analyze their behavior when changing the excitation wavelength. We report the optimal excitation conditions in terms of excitation laser wavelength for collecting the highest photocurrent signal and hence highlighting the photonic quantum ring behavior of the lasers.
