Abstract

"The performance of a Terahertz Optical Asymmetric Demultiplexer (TOAD) operating with an ordinary fiber and with a DDF and DIF (Dispersion Decreasing and Increasing Fiber) configurations, for three length of fiber (ξ= π/2, 2π and 5π) and using soliton and quasisoliton laser profile for the control pulse, was studied. We also did simulations with the TOAD operating with DDF in four different profiles: Hyperbolic, exponential, linear and Gaussian. Operating the TOAD using a DDF fiber one can say that the control power necessary to demultiplex the signal pulse is always lower compared with the TOAD with the normal telecommunication fiber. For all the profiles the increase of the length of the fiber also decrease the pump power of the three first peaks for the soliton and quasi-soliton regime."
