Optical Pulse Compression Using Rectangular Comb-Like Dispersion and Nonlinearity Profiled Fiber

Free registration required

Executive Summary

In this paper, the authors propose an optical pulse compressor which consists of a number of fiber units where a fiber unit is made of a certain length of Zero Dispersion Slope - Highly NonLinear Fiber (ZDS-HNLF) having higher nonlinearity and low dispersion followed by a certain length of Zero Dispersion Slope - Non-Zero Dispersion Shifted Fiber (ZDS-NZDSF) having a lower nonlinearity and higher dispersion. The resultant nonlinearity and dispersion profile of this fiber pair has a rectangular pattern and when a number of such fiber units are cascaded the overall nonlinearity and dispersion profile look like a comb.
