Complete mode structure analysis of tilted Bragg grating refractometers in planar waveguides toward absolute index measurement
Tilted Bragg grating refractometers are ideal devices for sensing applications. They work by diffracting light from a confined core mode into a series of well-defined cladding modes that are sensitive to the refractive index of an adjacent fluid. Using the Cauchy integral method, we find the modes o...
