Multiple nonlinear states of a Fabry-Perot (FP) laser under external optical injection and their applications are experimentally studied. The intensity noise of the FP laser has been demonstrated to be optimally suppressed under injection locking state, and the comparison between stable locking range and noise suppression range at different injection powers has been made. Photonic microwaves can be acquired at both period-one and period-two states. When an external RF signal is added to the FP laser operated at period-one state, its nonlinear state is switched to period-two state, which indicates the equivalence between external optical and electrical modulation added to the FP laser. At the same time, the photonic microwave linewidth can be obviously narrowed as an effect of external RF modulation.
