Figure 3: Photonic nanojet intensity in the micro-scale regime.
From: Integration of photonic nanojets and semiconductor nanoparticles for enhanced all-optical switching
The theoretical intensity of a photonic nanojet, calculated with Mie theory at the exit interface of a dielectric sphere, is shown as a function of the sphere’s refractive index, n, and diameter, d, for pump photoinjection at a wavelength of 780 nm. A trendline for the maximum intensity is shown as a solid grey curve. An intensity colourmap of Mie theory simulations in the micro-scale regime is shown on the left side of the figure—being the result of over a hundred thousand individual Mie theory simulations. The maximum (white) intensity is normalized for all n with constant d. Select 3D Mie theory simulations, with logarithmic intensities, are shown in the figure insets (a) a sphere with d=30 μm and n=1.83, and (b) a sphere with d=3 μm and n=1.76.
