Tamm mode electromagnetic cavity

摘要

Electromagnetic cavity (10, 20, 30, 40, 60) with Tamm modes having a resonant frequency in the THz domain, comprising: - an interference mirror reflecting in the THz domain consisting of a stack of dielectric layers (7) comprising an alternation, in a direction z, of two different layers, a so-called high refractive index layer (2) and a so-called low refractive index layer (4), the index of the low refractive layer being lower to that of the layer of high refractive index, manufactured by mechanical stacking of layers or by assembling dielectric layers one on top of the other - an upper metallic layer (5) deposited or transferred onto an upper dielectric layer of said interference mirror so as to form a structure supporting at least one Tamm mode in the THz domain.
