Cover Story: Continuous wave (cw) optically injected semiconductor lasers have important practical applications because optical injection can not only control the emitted wavelength but also increase the modulation bandwidth and relaxation oscillation frequency. Outside the injection locking region a cw optically injected laser displayed a wide range of dynamic regimes when the laser current of the master laser varied or was detuned. This figure shows the relative height of the oscillation intensity of the injected laser. In dark regions the intensity was either constant or pulsed regularly. In colored regions the height of the pulse was irregular, and the color code displays the height (relative to the mean) of the highest pulse. View this paper.
