Narrowband Filter

We report a graphene-based tunable ultra-narrowband mid-infrared filter which can be tuned from 4.45122 [Formula: see text]m to 4.44675 [Formula: see text]m by tuning the Fermi level from 0.2 eV to 0.6 eV. Furthermore, the reflection bandwidth is less than 0.2 nm and the reflection rate is more than 0.55. The ultra-narrowband filter is designed based on the guided-mode resonance (GMR) effect. The shift of reflection peak is mainly caused by the change of the real part of the graphene’s permittivity. This tunable ultra-narrowband mid-infrared filter can be applied in the mid-infrared microscopy.

We report a tunable bandpass mid-infrared filter with microstructure and graphene, and the transmission peaks can be tuned from [Formula: see text] to [Formula: see text] when the graphene’s Fermi level increases from 0.2 eV to 1.0 eV. This bandpass mid-infrared filter is originated from the guided-mode resonance (GMR) effect, and the tunable mechanism is mainly attributed to the change of the refractive index of the graphene. This tunable mid-infrared filter can be applied in non-dispersive infrared analyzer.

This paper presents a compact spectral detection system for common fluorescent and colorimetric assays. This system includes a gradient grating period guided-mode resonance (GGP-GMR) filter and charge-coupled device. In its current form, the GGP-GMR filter, which has a size of less than 2.5 mm, can achieve a spectral detection range of 500–700 nm. Through the direct measurement of the fluorescence emission, the proposed system was demonstrated to detect both the peak wavelength and its corresponding intensity. One fluorescent assay (albumin) and two colorimetric assays (albumin and creatinine) were performed to demonstrate the practical application of the proposed system for quantifying common liquid assays. The results of our system exhibited suitable agreement with those of a commercial spectrometer in terms of the assay sensitivity and limit of detection (LOD). With the proposed system, the fluorescent albumin, colorimetric albumin, and colorimetric creatinine assays achieved LODs of 40.99 and 398 and 25.49 mg/L, respectively. For a wide selection of biomolecules in point-of-care applications, the spectral detection range achieved by the GGP-GMR filter can be further extended and the simple and compact optical path configuration can be integrated with a lab-on-a-chip system.
