Operation at the single-photon level is beneficial for energy efficiency in optical and optoelectronic devices and opens new prospects for novel applications, ranging from quantum cryptography to quantum computations. In this regard, efficient single-photon sources operating upon electrical injection at room temperature are crucially important. Color centers in diamond are currently considered to...
The size of photonic components is fundamentally limited by the diffraction of light, while miniaturization is one of the key concepts in the development of high-speed and energy-efficient electronic and optoelectronic chips. Plasmonics attracts great interest thanks to the unique opportunity to confine light to a space much smaller than the light wavelength by converting it into surface plasmons...
We propose a novel scheme of the plasmonic cavity that is based on the insulator–metal–insulator (IMI) waveguide of finite length. Surface plasmon polaritons (SPPs) guided by the IMI structure can exhibit extremely small energy velocity if the metal film is thin enough. In that case, the losses are determined mainly by the intrinsic properties of the metal rather than the geometry of the cavity. Accordingly,...
