Ultralinear electro-optic modulators for microwave fiber-optic communications
Abstract
Three new EOM structures are proposed for high-efficiency nonlinearity compensation. A 30 dBc reduction in the third-order IMP is achieved at the expenses of a 2.9X driving voltage increase in the first approach. The second approach provides a theoretically total cancellation on the second- and third-order IMP at the expense of a 2.8X driving voltage increase. A 50 dBc reduction of third-order IMP is obtained, and a less than 100 dBc second- order IMP is achieved in the third approach at the expense of a 1.6X driving voltage increase. The sensitivity of the structure design parameters are also studied and discussed.
