Abstract: Starting from the multimode rate equations and concerning the fact of wavelength diffe rence of the spontaneous emission peak and gain peak,the intensity asymmetry of the longitudinal mode spectrum of the semiconductor laser biased below threshold is studied.The results indicate that the reason of the asymmetry is from the shorter peak wavelength of the spontaneous radiation than the gain peak wavelength.The experiment confirmed the theoretical prediction.
