Abstract

Conventional linearization techniques such as electrical pre-distortion or optical feedforward methods have been applied to Mach-Zehnder interferometer (MZI) modulators for CATV transmission systems. However, both methods can only ensure that the output of the MZI modulator meet the standard CATV requirements on composite second-order and composite triple beat, but cannot guarantee a satisfactory end-to-end system linearity. In this paper, we propose and demonstrate a novel linearization technique, which can simultaneously suppress the nonlinear distortions generated in a transmission system and increase the received carrier- to-noise ratio. This technique is based on offsetting the MZI bias voltage from its inflection point. Both analytical and experimental results are presented.
