Performance analysis of all optical time division multiplexed router based on terahertz optical asymmetric demultiplexer

摘要

Growing demands for bandwidth have stimulated the development of high-speed optical shared media networks. At present, most research on optical networking has concentrated on wavelength-division multiplexing (WDM). Optical time-division multiplexing (OTDM) is considered as an alternative to WDM offering data rates greater than 100 Gb/s using just a single wavelength. In such systems all optical routers, which overcomes the bottleneck of optoelectronic conversion, play an important role. This paper investigates TOAD based 1 X 4 optical router by developing a mathematical model. The proposed model is simulated and results for crosstalk are presented and compared with 1 X 2 router.
