Time-domain signature of an axially excited cholesteric liquid crystal. Part II: Rectangular wide-extent pulses
Abstract:Solving the Maxwell equations directly in the time-domain using a newly developed accelerated algorithm, we examine the response of axially excited layers of cholesteric liquid crystals (CLCs) to rectangular wide-extent pulses (WEPs). Although the circular Bragg phenomenon certainly distorts a rectangular WEP when its bandwidth substantially lies within the Bragg regime and the carrier wave's handedness coincides with the structural handedness of a CLC layer, the pulse edges are still transmitted and appropriately coded information is thus not lost.
