From: Measurement of Nanowire Optical Modes Using Cross-Polarization Microscopy
FEM simulated electric field distribution of HE11 (a) and TE01 (b) modes (NW diameter = 150 nm) illustrating how the mode is well confined within the NW at shorter wavelengths whereas at longer wavelengths the mode overlaps with the surrounding medium. The simulated color intensity maps showing where the HE11 (c) and TE01 (d) exist as guided modes. The color indicates the ratio of electric field distribution inside and outside the NW. The dashed areas denote areas where the modes have electric field partly outside the NW. These areas match to the measured and simulated bands in the cross-polarization spectra.
