We report on results of injection locking experiments with InAs/InP (100) Quantum Dot ring lasers, lasing in the 1.55µm wavelength region. Single mode operation (under external injection) with suppression of longitudinal modes of more than 35dB was shown on lasing direction agreeing with the injected signal. Counter propagating lasing is shown to be suppressed by as much as 18dB with measured power limited mostly by isolation of components rather than actual power. In addition, as expected from an injection locked laser, linewidth narrowing of 20 times was observed depending on the quality of the external laser used as the injection seed.
