WAVELENGTH SHIFTING OF GUIDE-MODE RESONANCE FILTER FOR SENSOR NETWORKS

摘要

In this paper, the wavelength shifting of Guided-mode resonance filter for sensor networks is investigated. It is demonstrated that the resonant wavelength will shift to longer wavelength as any one of parameters of guided-mode resonance filter increasing. And the period, the thickness of the grating change is liner related to the wavelength shifting. The characteristic of the wavelength drifting demonstrated in this paper can be useful for optical sensors systems and sensor networks.
