A team at Korea Advanced Institute of Science and Technology and at Electronics and Telecommunications Research Institute, both in Taejon, Korea, has demonstrated a photonic crystal laser with a hexagonal waveguide ring resonator. The photonic crystal structure improves the optical confinement of the device, potentially enabling higher output powers and minimizing loss. The optically pumped photonic crystal laser with an 8-µm-diameter hexagonal waveguide ring resonator displays a qualilty factor of greater than 2000 and a lasing threshold of 3mW at room temperature.
