Theoretical model of an interleave-chirped arrayed waveguide grating (IC-AWG)

摘要

In this paper, we propose a theoretical model for an Inter leave-Chirped Arrayed Waveguide Grating (IC-AWG), modifying the already existing formulation based on Fourier optics. With the IC-AWG is possible to achieve several functionalities in a single device, such as channel demultiplexing, polarization splitting and 90° optical hybrid operation. We also elaborate on the developed model to present a design procedure for the IC-AWG. Finally, the model validation through numerical simulations using real physical parameters obtained from manufactured devices available in the literature is performed.
