A InAlGaAs/InP microring laser with a ring width of 5 µm and an external radius of 10 µm, connected with a 2 µm‐wide output waveguide, is fabricated by the planar technology process. Continuous‐wave lasing operation is realised with a threshold current of 3 mA at 298 K, and 3 dB bandwidths of 10.8 and 8.7 GHz are obtained at the injection currents of 12 mA at 291 and 298 K, respectively.
