Abstract

One method of adjusting the characteristic deviations of Guided mode resonant filters (GMRFs) induced by preparing errors is derived by using the cover layer of GMRFs. The investigations of GMRFs are reported widely for their merits such as high efficiency, narrow bandwidth and low sideband. But there are few reports about the preparation and commercial application of GMRFs. The reason for this is that the characteristics of GMRFs are strict with the error of preparation. The data of this paper shows the linear relationship between the grating depth and the resonant wavelength in the grating depth error range of 0-12 nm. It is shown that the cover layer of GMRFs has adjusting effect on the characteristics of GMRFs. Through choosing material and adjusting the thickness of cover layer, these deviations induced by preparing errors cay be adjusted perfectly.
