Other Abstract

Electro-optic intensity modulation is usually based on linearity theorem. In some highly precise system, the nonlinear error analysis is significant for the property evaluation and error correction. Firstly, the light intensity modulation function was derived in detail under general condition. Then, the nonlinear errors as the system was running at the standard working point and around were analyzed. The expressions of the nonlinear errors above were given. The effect of ultra-harmonics on modulation was discussed. At last, the difference between actual modulation and ideal modulation were separately manifested in time domain to diverse modulation depths. Formula deduction and experimental analysis show that the high reliability of working point and small signal modulation can decease nonlinear error. These errors can be qualitatively and quantitively expressed, and the accuracy of electro-optic intensity modulation system can be improved through compensation.
