Paper Abstract

Paraxial optical systems implemented entirely with thin lenses and propagation through free space and/or Graded Index (GRIN) media are quadratic phase systems (QPS). The effect of any arbitrary QPS on an input wavefield can be described using Linear Canonical Transform (LCT). In this paper, we examine a novel numerical implementation of Fast Linear Canonical Transform (FLCT). We then apply the results in various optical signal processing applications.
