  • All-optical phase modulation using MZI-SOA
    Publication . Reis, Cláudia; Dionísio, Rogério Pais; Neto, Berta; André, P.S.; Teixeira, António
    This paper experimentally demonstrate an all-optical phase modulation technique using both arms of a Mach-Zehnder interferometer structure with Semiconductor Optical Amplifiers (MZI-SOA), with NRZ modulated signals driven at 10 Gbit/s. The proposed optical phase modulator can be used in multi-level modulation signals generation, as an optical routing element, as well in optical code division multiple access transmission systems.
