Abstract

Optical injection into a diode laser is a well-known method to induce and investigate highly-efficient nonlinear effects in semiconductor lasers.^[1,2] When injection occurs in the vicinity of a non-lasing longitudinal mode (intermodal injection), the slave laser can oscillate in three regimes schematically represented on Fig. 1, depending on the injected optical power Pinj and the frequency detuning δω = ω₁ - ω_inj between the master laser (noted E_inj) and the injected longitudinal side-mode (E₁).
