Abstract

We design a new double-layer grating template, which has the advantages of period uniformity, period number adjustability and continuous period regulation. Under the new template, we research the relationship between the spectrum and the grating templates: the resonant wavelength is mainly determined by the grating period; the intensity of transmission peak loss lies in the external pressures; the bandwidth of transmission spectrum can be controlled by the period number. Therefore, various applications can be realized by optimizing the transmission spectrum by reasonably selecting the matched parameters.
