Integrated subwavelength bimodal interferometer using a multilayer hyperbolic metamaterial

[EN] Bimodal interferometry can be implemented in a photonic integrated waveguide by inserting structures supporting¿at least¿two modes to connect an input and an output singlemode waveguide. The length of the bimodal section is inversely proportional to the index difference between the involved mod...
