“…21,22 Finally, EOT is an example of a Fano resonance, 23 often exploited in plasmonic nanostructures. [24][25][26][27] Surface plasmon lasing was recently reported in metal hole arrays, 10 thereby showing that surface plasmons in this structure can exist without loss. The hole array lases in a subradiant mode, which is a resonance with limited radiative loss.…”

In the past decade, metal hole arrays have been studied intensively in the context of extraordinary optical transmission (EOT). Recently it was shown that surface plasmons on optically pumped hole arrays can show laser action. So far, however, it is not demonstrated that the optical transmission of these arrays can also be increased using gain. In this Letter, we present a dramatic increase of the EOT via loss compensation of surface plasmons, accompanied by spectral narrowing of the resonance. These experiments allow us to quantify the modal gain experienced by the surface plasmon. Interestingly, the transmission minimum of the Fano-resonance becomes smaller.

“…Similar results were also discussed for purely dielectric spherical particles by Videen and Bickel 30 in 1992. Such behaviour is also associated with the directional Fano resonance [31][32][33] , when the scattering is strongly enhanced because of constructive resonant interference in one direction and suppressed in the opposite one. It can be achieved for example, in the system with two dipole-like excitations, one of them being at the resonance 34 .…”

Directional visible light scattering by silicon nanoparticles

et al. 2013

Directional light scattering by spherical silicon nanoparticles in the visible spectral range is experimentally demonstrated for the first time. These unique optical properties arise because of simultaneous excitation and mutual interference of magnetic and electric dipole resonances inside a single nanosphere. Such behaviour is similar to Kerker's-type scattering by hypothetic magneto-dielectric particles predicted theoretically three decades ago. Here we show that directivity of the far-field radiation pattern of single silicon spheres can be strongly dependent on the light wavelength and the nanoparticle size. For nanoparticles with sizes ranging from 100 to 200 nm, forward-to-backward scattering ratio above six can be experimentally obtained, making them similar to 'Huygens' sources. Unique optical properties of silicon nanoparticles make them promising for design of novel low-loss visible-and telecom-range metamaterials and nanoantenna devices.

“…The EIT/Fano effect discussed above requires gasphase three-level atoms, which greatly limits its applications. One recent fascinating development is the realization of EIT/Fano effect in solid-state optical microcavity systems and nanoscale plasmonic and metamaterial structures [59][60][61][62][63][64][65][66][67]. These optical systems possess resonant modes, which play the roles of the atomic energy levels.…”

Electromagnetically induced transparency in optical microcavities

Electromagnetically induced transparency (EIT)is a quantum interference effect arising from different transition pathways of optical fields. Within the transparency window, both absorption and dispersion properties strongly change, which results in extensive applications such as slow light and optical storage. Due to the ultrahigh quality factors, massive production on a chip and convenient all-optical control, optical microcavities provide an ideal platform for realizing EIT. Here we review the principle and recent development of EIT in optical microcavities. We focus on the following three situations. First, for a coupled-cavity system, all-optical EIT appears when the optical modes in different cavities couple to each other. Second, in a single microcavity, all-optical EIT is created when interference happens between two optical modes. Moreover, the mechanical oscillation of the microcavity leads to optomechanically induced transparency. Then the applications of EIT effect in microcavity systems are discussed, including light delay and storage, sensing, and field enhancement. A summary is then given in the final part of the paper.
