   Abstract

Design of electrooptic modulators in the applications of radio-over-fiber (ROF) has been studied and investigated in the present paper. Integrated optic design is handled to build a tank circuit to obtain the maximum output power. The modulated bandwidth is deeply and parametrically studied over wide ranges of the affecting sets of parameters via specially designed software which processes the interaction of causes and effects. The design parameters of the tank circuit have been processed over large operating requirements. The output due to the nonlinear distortion has been also analyzed, and its penalty is computed. Crystal modulator made of Potassium Dihydrogen Phosphate (KDP) crystal is processed.

Key words: Electrooptic modulators, radio over fiber, design.
