• The autostabilized light modulator at microwave frequency is analyzed by considering its resonance frequency shift. This analysis is based on thermal effects by heat produced in the modulator crystal by the microwave power and heat transfer from the crystal to an ambient medium. It is found that as long as the crystal temperature T does not exceed the transition temperature T_c of the crystal the state will be stable and the stability of the modulator is determined by the temperature dependence of dielectric constant and loss tangent of the crystal. The operation of the autostabilized modulator was examined by using an ADP crystal at 7GHz. This modulator is applied to the light transmission of video signals and the very successful results are obtained without any adjustments for a few days operation.
