Abstract: The present study is devoted to a theoretical investigation of coherent light signal homodyne detection with an injection-locked laser. In this detection method the external modulated light is injected into the cavity of the laser generating a single mode. The frequencies of the light signal and the laser should be near to each other. Information signal is detected in the bias circuit. We show the appearance of an additional noise due to the chaos excitation if the injected intensity is higher than $MIN@30 dBm. The fractal dimensions of the corresponding strange attractors are calculated. The effect of analog FM signals distortion is found. The reason is dependence of phase difference between external and laser radiations on frequency detuning. !7
