Abstract

The profile reshaping for a Gaussian beam reflected from a symmetrical metal-cladding waveguide is studied numerically and experimentally. For the thick guiding film, the distortion of a beam with very narrow frequency distribution is remarkable when the center wavelength of the beam locates in the resonant dip. This result compels us to question the validity of the method of using a position sensitive detector to measure the larger Goos–Hänchen (GH) shift. Therefore, a CCD is introduced to observe and record in real time the profile of the reflected beam, and the experiment conforms well to the simulations. The shaping technique developed in this paper promises much potential for optics devices based on the GH effect.
