Abstract: The distributed resonator model is used to show the presence of several resonance responses on the modulation characteristic of optically injection-locked Fabry–Perot lasers. The positions of the resonance peaks on the modulation characteristic are determined by the resonator length and frequency detuning of optical injection. It is shown that an appropriate choice of the resonator length and injection locking conditions allows one to obtain efficient modulation in two ranges near 40–60 GHz or to increase the direct modulation bandwidth up to 50 GHz.

Keywords: optical injection locking, coupled reduced equations, modulation characteristics, modulation bandwidth.
