中文摘要	directional emission triangle and square ingaasp/inp lasers have been fabricated by standard photolithography, inductively coupled plasma etching technique combined with wet chemical etching process. in this article, the characteristics of the microcavity lasers are presented. for an equilateral triangle microcavity laser with the side length of 30 mu m, we got the laser spectra fitted very well with the mode wavelength formulate lip to the 8(th) transverse mode at room temperature. but the laser spectra are usually more complex than the formulae for the lasers, especially for the lasers with a smaller side length. for a square microcavity laser with side length of 20 mu m, we observed the mode competition between the fabry-perot (fp) modes and whispering-gallery (wg) modes at 200k. the output spectra below the threshold have the mode interval of fp modes with a large mode interval, and the laser spectra agree very well with the wg modes, which have mode interval less than the fp modes. the output spectra are dominated by the fp modes below the threshold, because the fp modes have a higher output coupling efficiency than the wg modes.
