Abstract:	Transmission scanning near-field optical microscopy (T-SNOM) is a recently introduced method for imaging optical intensity distributions in dielectric waveguiding structures, with a resolution below the diffraction limit. It is in particular suitable for mapping out standing-wave patterns in resonators. Application of the method to a Fabry-Perot-like cavity in a line-defect waveguide in a photonic crystal slab is demonstrated. Two different two-dimensional models have been used to verify that the T-SNOM image is a good representation of the optical intensity distribution in the resonator.
