Abstract

We consider experimentally and theoretically the optical field dynamics of a five emitter laser array subject to a linearly decreasing injection current. We have achieved experimentally an array that produces a robust oscillatory power output with a nearly constant pi phase shift between the power in each waveguide and that linearly decreases in power as a function of waveguide number. This behavior persisted for pump currents varying between 380 and 500 mA with only a slight change in phase. Of note is the fact that the fundamental frequency of oscillation increases with injection current and higher harmonics are produced above a threshold current of approximately 380 mA. Experimental observations and theoretical predictions are in agreement.
