摘　　要：Mode competitions between modes with different output coupling efficiencies can result in optical bistability under certain asymmetric nonlinear gain. For a GaInAsP/InP equilateral triangle microlaser with the side length of 10μm, the drop of the output power with the increase of the injection current is observed corresponding to transverse mode transitions. Furthermore, the measured laser spectra up to 270K show that lasing modes coexist with the wavelength interval of 39nm at 240K. The emission at 5.2THz can be expected by the mode frequency beating with the 39nm interval.Mode competitions between modes with different output coupling efficiencies can result in optical bistability under certain asymmetric nonlinear gain.
