Abstract
In this paper, we 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 - nonzero 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. These cascaded fiber units form a rectangular comb-like dispersion and nonlinearity profiled (RCDNP) fiber. A cascade of ten such basic units can compress a 4.05 ps optical pulse down to 1.5 ps level.
