Experimental observation of evanescent modes at the interface to slow-light photonic crystal waveguides.
We experimentally study the fields close to an interface between two photonic crystal waveguides that have different dispersion properties. After the transition from a waveguide in which the group velocity of light is v(g) ~ c/10 to a waveguide in which it is v(g) ~ c/100, we observe a gradual increase in the field intensity and the lateral spreading of the mode. We attribute this evolution to ...
متن کاملExcitation of radiative and evanescent defect modes in linear photonic crystal waveguides
The dispersion of line-defect modes in silicon-on-insulator photonic crystal waveguides is explored by means of angleand polarization-resolved micro-reflectance measurements. The frequency-wave vector range accessible to the experiments is greatly expanded by the use of attenuated total reflectance, in addition to the standard one, thereby allowing one to study both truly guided (evanescent) an...
متن کاملNumerical Calculation of Resonant Frequencies and Modes of a Three-Atom Photonic Molecule and a Photonic Crystal in an External Cavity
In the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. First, governing formulation in transverse electric field mode (TE) is obtained using Maxwell equations. Then, an algorithm based on a finite difference scheme and matrix algebra is presented. The algorithm is then implemented in a comp...
متن کاملGrating-assisted superresolution of slow waves in Fourier space
We present a far-field optical technique allowing measurements of the dispersion relation of electromagnetic fields propagating under the light cone in photonic nanostructures. It relies on the use of a one-dimensional grating to probe the evanescent tail of the guided field in combination with a high-numerical-aperture Fourierspace imaging setup. A high-resolution spectroscopy of the far-field...
متن کاملBloch-mode extraction from near-field data in periodic waveguides.
We demonstrate that the spatial profiles of both propagating and evanescent Bloch modes in a periodic structure can be extracted from a single measurement of an electric field at the specified optical wavelength. We develop a systematic extraction procedure by extending the concepts of high-resolution spectral methods previously developed for temporal data series to take into account the symmet...
