Nonstandard FDTD Simulation-Based Design of CROW Wavelength Splitters
Figure 3
Wavelength splitter for multimode signals in an optical waveguide. Circular gray regions represent microdisks with excited WGMs. Linear gray regions represent an optical waveguide. and are the radii of disks and , respectively. is the gap spacing between disks ( analogously defined). Source is a superposition of wavelengths and . Disks and are excitable only by and , respectively.
