In this paper the analysis of Stimulated Raman Scattering induced crosstalk in Subcarrier Multiplexed WDM system has been discussed. The expression for SRS induced crosstalk have been observed for different fiber types such as single mode fiber, dispersion compensation fiber, non-zero dispersion shifted fiber and non-zero dispersion fiber. Comparison of different fibers is done at varying trans...

For optical communication links using wavelength-division multiplexing over a long-haul fiber optic backbone, stimulated raman scattering may lead to significant transmission impairment. This paper discusses the enhanced analysis for the SRS induced crosstalk in the optical networks. The expression for Stimulated Raman Scattering induced crosstalk have been observed at different fiber types( as...

Elliptical scatterers possess the properties of anisotropy and multiple degrees of freedom. With the plane wave expansion method, the slow light effect with high ng and low dispersion can be achieved by optimizing the structure parameters of photonic crystal waveguide with line defect, including changing the length of major axis or minor axis, and rotating scatterers relative to the direction o...

Here, we study the characteristic feature of conventional (ON-OFF keying) and soliton based transmission system. We consider 20Gbps transmission system implemented with Conventional Single Mode Fiber (C-SMF) to examine the role of Gaussian pulse which is the characteristic of conventional propagation and Hyperbolic-secant pulse which is the characteristic of soliton propagation in it. We note t...

58 Abstract— In this paper the performance of optical fiber communication system is analytically investigated on account of fiber chromatic and polarization mode dispersion employing OFDM-QAM. The influence of the dispersions on the signal spectrum is determined as a function of fiber length, Bit rate and dispersion parameters for intensity modulation/ direct-direct (IM/DD) receiver. It is foun...

It is required to suppress or mitigate the optical signal distortion due to group velocity dispersion and optical Kerr effects in ultra-high speed and long-haul transmission systems. Dispersion management (DM), optical phase conjugation (OPC), and the combination of these two are promising techniques to compensate for the signal distortion. The goal of this paper is to investigate the possibili...

We have numerically investigated supercontinuum generation in photonic crystal fibers with zero-dispersion wavelengths in the vicinity of 800 nm by using an input pulse with a peak power of about 20 kW and a width of about 10 fs. The effects of fiber dispersion and the input pulse parameters on the generated optical spectra are quantitatively analyzed. The propagation length necessary for the g...

In this paper, we calculate the spectrum of scalar field fluctuations in a bouncing, asymptotically flat universe, and investigate the dependence of the result on changes in the physics on length scales shorter than the Planck length which are introduced via modifications of the dispersion relation. In this model, there are no ambiguities concerning the choice of the initial vacuum state. We st...

The minimized dispersion and controllable dissipation (MDCD) reconstruction technique optimizes dispersion and dissipation separately and shows desirable properties of both dispersion and dissipation. A low dispersion finite volume scheme based on MDCD reconstruction is proposed which is capable of handling flow discontinuities and resolving a broad range of length scales. Although the proposed...
