Spectral properties of an optically injection-locked semiconductor laser are analytically calculated and are experimentally verified the locking bandwidth is comparable to or smaller than the linewidth of a slave laser. In this case, the spectral lineshape becomes non-Lorentzian and its linewidth strongly depends on the locking bandwidth.
