Interleaved and Chirped Array Waveguide Grating

Abstract

[ES] El principal objetivo de este trabajo es el desarrollo de un modelo teórico para describir un array waveguide grating (AWG) con ligeras modi¿caciones que permiten emplearlo como un bloque fundamental en un receptor coherente homodino con diversidad en fase y polarización.

[EN] The theoretical analysis of an interleaved and chirped array waveguide grating as a polarization-diversity and dual-quadrature coherent receiver is described in this document. The model describes how multiple focusing points per wavelength can be obtained through array interleaving, and with precise phase di¿erences amongst them through chirping. Finally, how the model describes the operation as hybrid and polarization diversity receiver is shown.
