Rayleigh limit scatering
WebThe name “Rayleigh scattering” is mostly associated with light scattering by molecular and atomic gases and the related question “Why is the sky blue?”1,2 In addition, the name Rayleigh is commonly attached to scattering by small particles in the expressions “Rayleigh regime” or “Rayleigh limit,” in which small refers to a size ... WebUsing a combination of resist reflow to form a highly circular etch mask pattern and a low-damage plasma dry etch, high-quality-factor silicon optical microdisk resonators are fabricated out of silicon-oninsulator (SOI) wafers. Quality factors as high as Q=5×106 are measured in these microresonators, corresponding to a propagation loss coefficient as …

WebThe Rayleigh scattering of light, which is spatially separated from the zeroth order (direct) illuminating light, is collected with an objective with a smaller N.A. The acquired sample image only shows the scattering centers as bright spots on a dark background, similar to a fluorescence microscopic image. Figure 4.1.
