Název v původním jazyce

Optical fiber Bragg grating used in the sensing of surface plasmon resonance

Popis výsledku v původním jazyce

We introduce two types of optical fiber Bragg grating sensor with nanoscale spatial resolution and chemical specificity. This sensing technique holds promise for gaining deeper insight into the functionality of nanoscale structures superposed on the goldthin film or embedded in its complex environments. The techniques are based on the effect of surface plasmon resonance and surface plasmon resonance fluorescence. Properly p-polarized laser light illuminates the Bragg grating and induces a strongly enhanced field at the gold thin film. This is due to the coupling of guided mode of the optical fiber and surface plasmon mode. The laboratory prototype of sensor with linear Bragg grating is used for the measurement of smooth variances in refractive index and a sensor with oblique Bragg grating combined with the Scanning near field optical microscope is used for the measurement of analyte thickness. Here, the spatial resolution is determined by the tip size (typically on the order of 60-80
