title: Harmonic and intermodulation performance of cascaded electro-optic modulators.
abstract: Closed-form analytical expressions are presented for predicting the harmonic and intermodulation performance of electro-optic modulators synthesized from Mach-Zehnder, directional coupler, and y-fed coupler modulators. The special case of an electro-optic modulator excited by a two-tone signal is considered in detail, and the results are compared with previously reported results obtained by using a fast Fourier transform.
