Abstract
An optical modulator includes first and second modulator segments. The first and second modulator segments form an optical signal path for an optical signal. The optical modulator also includes an electrical signal path capable of receiving and carrying a modulation signal, which is applied to the optical signal at the first and second modulation segments to generate a modulated optical signal. An inductive element may be disposed between electrical inputs to the first and second modulator segments. The optical modulator may be an electro-absorption modulator (EAM). The inductive element may be an inductor or a transmission line segment.
