“…In the synchronization regime, to compensate these effects there appear some energy fluxes. In the direction parallel to the dipole moments, the far fields are equal to zero and energy transfer needs a space gradient of the phase [20]. In the transverse direction, the energy transfer is performed by far field that does not need a phase gradient.…”

We demonstrate that interacting spasers arranged in a 2D array of arbitrary size can be mutually synchronized allowing them to supperradiate. For arrays smaller than the free space wavelength, the total radiated power is proportional to the square of the number N of spasers. For larger arrays, the radiation power is linear in N. However, the emitted beam becomes highly directional with intensity of radiation proportional to N 2 in the direction perpendicular to the plane of the array. Thus, spasers, which mainly amplify near fields, become an efficient source of far field radiation when they are arranged into an array. . Schematically, the spaser is an inversely populated two-level system (TLS), e.g. an atom, a molecule, or a quantum dot, interacting with a plasmonic nanoparticle (NP) [4,6] or with a plasmonic waveguide via near field [7][8][9]. The transition from the excited to the ground state is accompanied by oscillations of the TLS dipole moment. These oscillations excite surface plasmons at the NP. Due to the short distance between the NP and the TLS, plasmon generation is much more efficient than photon radiation. In turn, plasmon oscillations induce the TLS to radiate providing feedback for the spaser.

“…When we have a single wave, reactive components do not contribute to its intensity. However, when reactive components of a field of two waves superpose, an energy IF is formed in the direction in which no energy transfer occurs for a single wave [1,2]. The contribution from the IF to the energy transfer when light is incident on the interface between the transparent and absorbing media was pointed out in [3,4].…”

Interference effect during oblique incidence of counter-propagating waves on an absorbing layer

et al. 2014

View full text Add to dashboard Cite

Features of energy flux formation inside and outside an absorbing layer are theoretically described for the case where two coherent counter-propagating waves of identical linear polarization are obliquely incident on the opposite sides of the layer with the adjacent media exhibiting symmetric optical parameters. Dependence of the interference fluxes on the angle of incidence and thickness of the layer is established for different phase shifts of the incident waves. Conditions under which the energy density inside the layer attains the maximum value are determined.
