title: Near field imaging of a GaAs photonic crystal cavity and waveguide using a metal coated fiber tip.
abstract: We report optical near field characterization of a GaAs photonic crystal waveguide which is side coupled to a nano cavity. We observe the effect of the metal coated probe on the resonance wavelength and the intensity distribution. The measurements fit well to finite difference time domain simulations.
