Reconfigurable reflective arrayed waveguide grating using optimization algorithms

Abstract

[EN] In this paper we report the experimental realization of a reconfigurable reflective arrayed waveguide grating on silicon nitride technology, using optimization algorithms borrowed from machine learning applications. A dozen of band-shape responses, as well as a spectral resolution change, are demonstrated in the optical telecom C-band, alongside a proof of operation of the same device in the O-band. In the context of programmable and reconfigurable integrated photonics, this building block supports multi-wavelength/band spectral shaping of optical signals that can serve to multiple applications.Ministerio de Economia y Competitividad (Industrial doctorate grant DI-15-08031, PID2019110877GB-I00 BHYSINPICS, TEC2016-80385-P SINXPECT); H2020 Marie Sklodowska-Curie Actions (Training Network MICROCOMB (GA 812818)); Generalitat Valenciana (PROMETEO/2017/103).Fernández, J.; Felip, J.; Gargallo, B.; Doménech, JD.; Pastor Abellán, D.; Domínguez-Horna, C.; Muñoz Muñoz, P.
