A temperature-insensitive Bragg grating sensor - using orthogonal polarisation modes for in situ temperature compensation
An exposed Bragg grating incorporated into a planar waveguide forms an optical device that acts as a refractive index sensor. The exposed evanescent field causes the Bragg peak to be sensitive to the refractive index of its surroundings and can be used to detect changes in this environment. The meth...
