Paper Abstract
In the present communication, a procedure for the synthesis of an optical finite impulse response (FIR) birefringent filter
generating arbitrary spectral output is presented. The basic filter consists of a cascaded system of n identical retarders
between two polarizers at the two ends. A mathematical model of the optical FIR filter is introduced using the FIR
theory of digital filter design. The parameters determined by the synthesis procedure are the angles of the optic axes of
the individual crystals and the angle of the output polarizer. Classical FIR filter design method along with the optical
backward transfer technique has been used. Two different arbitrarily specified spectral output profiles have been studied.
However, the method is equally applicable for any periodic transfer function whose corresponding impulse response is
real and causal.
