Abstract
Techniques (e.g., implemented in devices, methods and/or in non-transitory storage units) are used for confining wavelengths, e.g., using a pillar photonic crystal. A semiconductor device includes a pillar photonic crystal including a structure and a plurality of pillars extending from the structure in a height direction, wherein the plurality of pillars form at least one waveguide for electromagnetic radiation at a specific wavelength, the at least one waveguide extending in at least one planar direction, wherein the structure includes a confining layer in doped semiconductor material to support propagation of surface plasmon polaritons.
