All optical photonic crystal based logic gates are believed to be essential components for compact photonic integrated circuits and Wavelength Division Multiplexing (WDM) systems. One of the promising designs for a logic gate is based on the photonic crystal ring resonators (PhCRR). In this paper, we carried out a performance analysis of a new simple shape of a PhCRR as a function of the nonlinear...
In this paper, an optical Ultra Dense Wavelength Division Multiplexing (UDWDM) system based on the combination of advanced modulation formats and multi-diagonal code with an ultra high transmission capacity of 2 Tb/s using different modulation formats is developed; 100 channels with channel spacing of 0.4 nm and 0.2 nm are studied in order to find the optimum modulation format for a high bit rate...
Wavelength division multiplexing is used to design and to realize multi-channel optical communication systems to meet the growing demand for bandwidth. Dense wavelength division multiplexing (DWDM) technique, characterized by channel spacing equals or less than 0.8 nm or the use of more than 16 channels, offers the full use of the fiber bandwidth. Therefore, it is the perfect means of network enlargement...
