Dispersion measurement of arrayed-waveguide gratings by Fourier transform spectroscopy

Dispersion measurement of arrayed-waveguide gratings by Fourier transform spectroscopy

Fourier transform spectroscopy is applied to measure the chromatic dispersion of arrayed-waveguide gratings. Since this method is commonly used to determine the amplitude and phase errors of a waveguide grating, complete characterisation can be performed by one measurement.
