A expressão analítica para o espectro de transmissão de redes de fibra de longo período em cascata é apresentada de forma fechada. Quando várias redes idênticas são colocadas em cascata em série com uma distância regular, o espectro de transmissão revela ter uma série de picos regularmente espaçados, adequados para filtros multicanais. A solução analítica é obtida diagonalizando a matriz de transferência de cada unidade de grade que é composta por uma única grade e uma região livre de grade entre grades adjacentes. O espectro do dispositivo é descrito de forma simples com o número de grades em cascata e um único parâmetro que contém a informação da diferença de fase entre os modos. Com a equação derivada, os comportamentos espectrais do dispositivo proposto são investigados. A intensidade de cada pico pode ser controlada ajustando a resistência de uma única grade. A separação entre grades adjacentes determina o espaçamento entre os picos. A sutileza dos picos pode ser aumentada colocando mais grades em cascata. Os resultados analíticos derivados são comparados com os resultados conhecidos de redes emparelhadas e redes com mudança de fase.

Abstract: The analytic expression for the transmission spectrum of cascaded long-period fiber gratings is presented in a closed form. When several identical gratings are cascaded in-series with a regular distance, the transmission spectrum is revealed to have a series of regularly spaced peaks, suitable for multi-channel filters. The analytic solution is obtained by diagonalizing the transfer matrix of each grating unit that is composed of a single grating and a grating-free region between adjacent gratings. The spectrum of the device is simply described with the number of cascaded gratings and a single parameter that has the information of the phase difference between the modes. With the derived equation, the spectral behaviors of the proposed device are investigated. The intensity of each peak can be controlled by adjusting the strength of a single grating. The separation between adjacent gratings determines the spacing between the peaks. The finesse of the peaks can be increased by cascading more gratings. The derived analytic results are compared with the known results of paired gratings and phase-shifted gratings.
