WebOptical modulation with pre-chirp control using electro-absorption modulator (EAM) and its integration have been reviewed. Device design, fabrication, and application of high-speed chirp-control inte WebThe basic principle of OCDM consists of multiplexing a number of chirp waveforms that are mutually orthogonal with each other and sharing the same bandwidth and time slot. With respect to single chirp modulation, OCDM increases the transmitted data rate by overlapping data in both the time and chirp domain.
