The coupling characteristics of a novel kind of directional couplers composed by two parallel non-conventional waveguides are theoretically analyzed in details.The coupling length as a function of the operating wavelength ...

Waveguides with high contrast of refractive indexes between the core and the cladding, usually present considerable scattering losses in the imperfections of the core walls. A possible solution to solve this problem can ...

Neste trabalho, acopladores direcionais híbridos, compostos por guias de ondas dielétricos e metálicos, foram analisados em detalhes por simulações computacionais utilizando o Método dos Elementos Finitos (MEF). A resposta ...
