From: Efficient color routing with a dispersion-controlled waveguide array
The calculation result of tricolor separation in a color waveguide matrix, with the initial field distribution described by a Gaussian function with an FWHM of 28 µm, the Gaussian beam maximum is located at x=0. Here, the red, green and blue represent the light wave at 611, 544 and 434 nm respectively. The propagation of the wavelengths 434, 544 and 611 nm is shown in detail in (b), (c) and (d), respectively. FWHM, full width at half maximum.
