Abstract

A modulator design capable of producing a new constant intensity modulation format is proposed. The modulator consists of a Mach–Zehnder interferometer containing two polarization modulators. By shifting the relative phase of the electrical drive signal applied to each polarization modulator by 90° a modulation consisting of a carrier and a single sideband, polarized orthogonal to the carrier, is produced.
