This work proposes a new energy efficient method for generating two mutually coherent laser lines. This method combines mutual optical injection locking with external modulation, which can be implemented with an electro-absorption modulator (EAM). Numerical simulations demonstrate that the proposed method is feasible within a narrow locking range. In addition, it is demonstrated that suppressing the optical carrier of the modulated signal extends the locking range by a factor of 3.
