DISPERSION EFFECTS IN OPTICAL MILLIMETER-WAVE SYSTEMS USING SELF-HETERODYNE METHOD FOR TRANSPORT AND GENERATION

This paper describes the detrimental effects of chromatic and polariza tion mode dispersion (PMD) on systems using single-laser-based optical self-heterodyning for generation and transport of millimeter (mm)-wav e signals. The decrease of the generated mm-wave power due to chromati c dispersion in conjunction with nonnegligible laser phase noise is ca lculated and experimentally verified. Considering statistical properti es of the PMD an analytical expression for the cumulative probability distribution of the power penalty is found and used td determine the r equired system margin for a given system outage rate. Furthermore, two system experiments using ASK and DPSK modulation scheme, respectively , are presented showing no limitation due to the dispersion effects.
