中文摘要	mode characteristics of equilateral triangle resonators (etrs) are analyzed based on the symmetry operation of the point group c-3v. the results show that doubly degenerate eigenstates can be reduced to the a(1) and a(2) representations of c-3v, if the longitudinal mode number is a multiple of 6; otherwise, they form the e irreducible representation of c-3v. and the one-period length for the mode light ray is half of the perimeter of the etr. mode q-factors are calculated by the finite-difference time-domain (fdtd) technique and compared with those calculated from far-field emission based on the analytical near-field pattern for te and tm modes. the results show that the far-field emission based on the analytical field distribution can be used to estimate the mode q-factor, especially for tm modes. fdtd numerical results also show that q-factor of te modes reaches maximum value as the longitudinal mode number is a multiple of 7. in addition, photoluminescence spectra and measured q-factors are presented for fabricated etr with side lengths of 20 and 30 mu m, and the mode wavelength intervals are compared with the analytical results.
