On the Use of SOA-Based Tunable Dispersion Compensator in Ultrafast Incoherent Fiber-Optic CDMA Systems Under Temperature Variation

Abstract

The use of semiconductor-optical-amplifier-based tunable dispersion compensator (SOA-TDC) in ultrafast incoherent fiber-optic code-division multiple-access (FO-CDMA) systems with picosecond multiwavelength codes has recently been demonstrated. In this paper, results on the SOA-TOC's capability of compensating for fiber chromatic dispersion and distorted autocorrelation function caused by fiber temperature variation (FTV) in such a FO-CDMA system with a long fiber link are reported. The deleterious effects of FTV to the system performance are quantified in terms of "chip granularity" and studied by applying a recent multiple-QoS performance-analytical model.
