Broadband waveguide intersection with low crosstalk in two-dimensional photonic crystal circuits by using topology optimization.
Topology optimization has been used to design intersections in two-dimensional photonic crystal slab waveguides. We have experimentally confirmed that the optimized intersection displays high-transmittance with low-crosstalk for the straightforward beam-propagation line.
