The theoretical study on the effect of the avalanche-injection diode supply current upon the oscillator operation mode has been conducted. As additional parameters, affecting its operation regime, the coefficients of signal reflection from the inhomogeneity in the output transmission line and the value of this signal time delay have been considered. It has been shown that with the different ratios of these parameters in the oscillator the following modes may occur, such as synchronization, with the amplitude instability, multi-frequency, dynamic chaos, one-frequency and oscillation suppression modes. The analysis of possible modes of the operation of the oscillator on the avalanche-injection diode has been performed based on the solution of the auto-oscillator equation. The obtained results permit to evaluate the region of the parameters, with which the negative effect upon the oscillator operation mode will be absent as well as the regions of the oscillator parameters, with which the dynamic chaos generation mode can be obtained.

Based on the avalanche diode theoretical model, reflecting not only the avalanche multiplication of charge carriers but also, the processes proceeding in the diode interval under the condition of its irradiation by optical beam, the avalanche diode impedance properties, which allow calculating the MW -modulating and demodulating properties of the optical region, have been determined.

The possibility of the microwave amplitude-modulated optical vibrations detection via synchronizing the avalanche-diode oscillator by this microwave signal has been considered. The general properties of the oscillator-modulator have been discussed.
