Microcylinder resonators with multiple ports connected to waveguides are investigated by 2D finite-difference time-domain (FDTD) simulation for realizing microlasers with multiple outputs. For a 10 um radius microcylinder with a refractive index of 3.2 and three 2 um wide waveguides, confined mode at the wavelength of 1542.3 nm can have a mode Q factor of 6.7 x 104 and an output coupling efficiency of 0.76. AlGaInAs/InP microcylinder lasers with a radius of 10 um and a 2 um wide output waveguide are fabricated by planar processing techniques. Continuous-wave electrically injected operation is realized with a threshold current of 4 mA at room temperature, and the jumps of output power are observed accompanying a lasing mode transformation.
