Resumo: Grid couplers have become a key element in converting optical-to-electronic (electronic-to-optical) signals into communication systems using optical fibers and waveguides. Although this interest has motivated considerable progress in recent years, with a variety of proposals in the literature, its implementation remains limited due to the principle of operation. In particular, grids are conventionally designed using the Bragg principle, which ends by limiting operation to a specific wavelength (frequency). In this work, we present a new concept of grid coupler, called a quasi-periodic grid, with which we not only achieve a broadband coupling response, but also the coupling for multiple wavelengths in the region of frequencies of interest. The unit cell of each structure was designed following the Fibonacci sequence to control the degree of disorder in the structure. All of our results were obtained using the finite difference in the time domain method (FDTD), with simulations performed in the commercial software Lumerical FDTD Solution. It is hoped that our proposal can lead to the development of platforms that allow to meet the growing market demand for greater capacity and bandwidth in optical communications.

Embora esse interesse tenha motivado um progresso consider??vel nos ??ltimos anos, com uma diversidade de propostas na literatura, sua implementa????o continua limitada devido ao princ??pio de funcionamento. Em particular, as grades s??o convencionalmente desenhados usando o princ??pio de Bragg, que termina limitando o funcionamento a um comprimento de onda (frequ??ncia) espec??fico. Neste trabalho, apresentamos um novo conceito de acoplador de grade, chamado de grade quase-peri??dico, com o qual n??o s?? conseguimos uma resposta de acoplamento de banda larga, mas tamb??m o acoplamento para m??ltiplos comprimentos de onda na regi??o de frequ??ncias de interesse. A c??lula unit??ria de cada estrutura foi desenhada seguindo a sequ??ncia de Fibonacci para termos um controle do grau de desordem na estrutura. Todos os nossos resultados foram obtidos usando o m??todo de diferen??as finitas no dom??nio do tempo (FDTD, sua sigla em ingl??s), com simula????es realizadas no software comercial Lumerical FDTD Solution. Espera-se que a nossa proposta possa levar ao desenvolvimento de plataformas que permitam atender ?? crescente demanda do mercado por maior capacidade e largura de banda nas comunica????es ??pticasSubmitted by Tede Dspace (tede@inatel.br) on 2021-11-23T14:04:53Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Desenho e an??lise de grades quase-peri??dicas tipo Fibonacci.pdf: 22423676 bytes, checksum: cd1ac050a9a1466d29a65cca4e51d65d (MD5)Made available in DSpace on 2021-11-23T14:04:53Z (GMT).
