Abstract

The characterization of integrated optic devices with the Wigner transform is presented. The Wigner transform of planar waveguides, waveguide couplers and optical modulators is computed. It allows the determination of various parameters of the integrated optic devices such as the parity and shape of waveguide modes, the effective numerical aperture, the distance between coupled waveguides, the coupling efficiency, etc. Also presented are the set-ups for the Wigner transform measurement in different phase space coordinates as space-angle and time-frequency
