Directional emission semiconductor microcavity lasers integrated with semiconductor planar technique are potential light sources for photonic integrated circuits. In this article, we investigate mode characteristics for equilateral triangle and square microcavities for realizing directional emission microcavity lasers. The analytical mode field distributions and mode wavelengths are presented for two-dimensional (2D) triangle and square resonators, and directional emission are simulated by finite-difference time-domain (FDTD) technique. The numerical results of mode Q-factors and output coupling efficiencies for the triangle and square resonators show that high efficiency directional emission microcavity lasers can be realized by directly connected an output waveguide to the resonators, because the mode field patterns are standing distributions in the triangle and square resonator. Laser output spectra of fabricated InGaAsP/InP triangle lasers are compared with the analytical results.
