“…[1][2][3] Unlike a surface plasmon polariton, TPP can be excited by optical radiation of any polarization without phase matching. 4 Various nanophotonic devices such as lasers, 5 optical switches, [6][7][8] ideal absorbers, [9][10][11] thermal emitters, 12 single photon sources, 13 photodetectors, [14][15][16][17] and sensors [18][19][20][21] were proposed on the basis of the TPP. The TPP can be coupled with other types of modes, with their simultaneous excitation in the system.…”
