Abstract :
An analysis is given on the modified phase reversal structure of electro-optic modulators. It is shown that the bandwidth to half-wave voltage ratio (BVR) increases with the number of phase reversal sections. Under the assumption that the number of electrode sections is M, a set of M-elements second-order nonlinear equations has been derived and solved by Newton´s iteration method. The calculated results provide the optimum overlap integral for each section of a phase reversal modulator in order to “flatten” the frequency response of the device
