Evanescent field imaging of an optical fiber Bragg grating
We have investigated the evanescent field associated with an optical fiber Bragg grating using the sub-wavelength imaging properties of scanning near-field optical microscopy (SNOM). Imaging of either the field distribution within the grating, or the periodic refractive index changes along the grati...
