Analysis of Dispersion Characteristics of Planar Waveguides via Multi-Order Interrogation of Integrated Bragg Gratings

We demonstrate experimentally a simple technique to measure the wavelength-dependent effective refractive index of a waveguide utilizing integrated Bragg grating structures. A broadband measurement of the Bragg wavelengths yields the effective index of the waveguide and, thus, an accurate total disp...
