A GaInAsP photonic crystal nanolaser was operated by resonant optical pumping in which the effective cavity area was selectively excited. The laser mode intensity was markedly enhanced when the pump wavelength was tuned to a higher-order cavity mode, and room-temperature continuous-wave lasing was obtained in the fundamental mode. Furthermore, the switching behavior due to a modal wavelength shift was clearly observed, suggesting the possibility of bistable operation, and so on.
