We present an approach of counting high order nonlinear optical (NLO) effects on coupling efficiency, resonance wavelength, and optical bistability of semiconductor microring resonators. In our study, we include Kerr effect, two-photon absorption (TPA), free-carriers (FC), and loss. Unlike to previous studies, we included intensity-dependent coupling coefficients effects on resonance wavelength shift and optical bistability behavior, in addition to the other NLO effects. The results show light transmission between couplers decreases at high light intensities. Also, a blue shift is seen on resonance wavelength of microring in nonlinear regime. Optical bistability of microring is dramatically affected at high light intensity, too. Instability of microring operation due to NLO effects at very high light intensities is reported.
