Abstract

Port output of metallo-dielectric confined circular microlasers directly connected with a coupling waveguide in radial direction is presented and numerically investigated by the finite-difference time-domain method and the Padé approximation. The quality factors of fundamental whispering-gallery modes confined in microlasers with dimensions of around 1 μm do not deteriorate until the output waveguide can support a one-order guided wave. The port-output metallo-dielectric microlasers with low threshold are expected. In addition, the mode characteristics of port-output metallo-dielectric microlasers are studied based on ample modes of larger cavity, where coupled modes and standing-wave-like modes dominate in the cavity with a wide output port.
