Scientific paper

A coherent array of 10 amplifiers has been demonstrated using an active integrated optics technology based on AlGaAs laser diode material. These arrays have demonstrated power outputs of 300 mW CW with only 2 mW injected power. The fractional coherence between any two amplifiers in the array is greater than 0.8. These arrays have been used to amplify a 10 MHz amplitude-modulated signal, which is the first step in the development of a laser communications system.
