We present a method of lasing mode control by taking advantage of phase-shifted grating for multielectrode distributed feedback lasers. By applying this method to stabilize the dual lasing modes, we demonstrated not only self-pulsating through beating phenomena, but also optical injection locking for external signals at very high frequency regions.
