Paper Abstract

The general idea of the present investigations is to use both TE and TM polarization of electromagnetic wave in high resolution scanning differential heterodyne microscope to get information about width and depth of deep and narrow metalized rectangular grooves. The main application of the method is the characterization of plasmon polariton waveguides. Using rigorous diffraction theory we have demonstrated the difference in periodic depth dependences of phase and amplitude contrast of microscope response for TE and TM polarization of probing beams. We have also proposed a method of depth and width control for grooves in case of a phase inversion of response.
