Evanescent field imaging of an optical fiber Bragg grating
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 grating can be performed by tuning the launched light on or off the grating resonance. These measurements reveal non-uniformity in the resonant standing-wave pattern that occur due to phase errors in the refractive index profile of the grating under study.

Abstract
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 grating can be performed by tuning the launched light on or off the grating resonance. These measurements reveal non-uniformity in the resonant standing-wave pattern that occur due to phase errors in the refractive index profile of the grating under study.
