| 中文摘要 | square microcavity laser with an output waveguide is proposed and analyzed by the finite-difference time-domain (fdtd) technique. for a square resonator with refractive index of 3.2, side length of 4 microns, and output waveguide of 0.4-micron width, we have got the quality factors (q factors) of 6.7×10~2 and 7.3×10~3 for the fundamental and first-order transverse magnetic (tm) mode near the wavelength of 1.5 microns, respectively. the simulated intensity distribution for the first-order tm mode shows that the coupling efficiency in the waveguide reaches 53%. the numerical simulation shows that the first-order transverse modes have fairly high q factor and high coupling efficiency to the output waveguide. therefore the square resonator with an output waveguide is a promising candidate to realize single-mode directional emission microcavity lasers. |
