  • Abstract
    Square microresonators with circular corners and a center air hole are simulated by the finite-difference time-domain (FDTD) technology and Padé approximation method. The results show that the deformed square resonators can increase mode Q factor at certain conditions. Furthermore, the hole in the square resonator can not only enhance the Q factor and the output coupling efficiency, but also have the ability to select the lasing mode.
