Monolithic metallic nanocavities for strong light-matter interaction to quantum-well intersubband excitations.

چکیده
We present the design, realization and characterization of strong coupling between an intersubband transition and a monolithic metamaterial nanocavity in the mid-infrared spectral range. We use a ground plane in conjunction with a planar metamaterial resonator for full three-dimensional confinement of the optical mode. This reduces the mode volume by a factor of 1.9 compared to a conventional metamaterial resonator while maintaining the same Rabi frequency. The conductive ground plane is implemented using a highly doped n+ layer which allows us to integrate it monolithically into the device and simplify fabrication.

Far-infrared absorption in parallel quantum wires with weak tunneling.
We study collective and single-particle intersubband excitations in a system of quantum wires coupled via weak tunneling. For an isolated wire with parabolic confinement, the Kohn's theorem guarantees that the absorption spectrum represents a single sharp peak centered at the frequency given by the bare confining potential. We show that the effect of weak tunneling between two parabolic quantum...
متن کاملUltrafast and Nonlinear Plasmon Dynamics
The interaction of light with a metal mediated by surface plasmon polaritons provides for sub-diffraction limited optical confinement and control. While the relationship of the linear plasmon response to the underlying elementary electronic excitations of the metal is well understood in general, the corresponding ultrafast and nonlinear plasmon interactions could provide further enhanced functi...
متن کاملIntrasubband and Intersubband Electron Relaxation in Semiconductor Quantum Wire Structures
We calculate the intersubband and intrasubband many-body inelastic Coulomb scattering rates due to electron-electron interaction in two-subband semiconductor quantum wire structures. We analyze our relaxation rates in terms of contributions from interand intrasubband charge-density excitations separately. We show that the intersubband (intrasubband) charge-density excitations are primarily resp...
متن کاملControlling light localization and light-matter interactions with nanoplasmonics.
Nanoplasmonics is the emerging research field that studies light-matter interactions mediated by resonant excitations of surface plasmons in metallic nanostructures. It allows the manipulation of the flow of light and its interaction with matter at the nanoscale (10(-9) m). One of the most promising characteristics of plasmonic resonances is that they occur at frequencies corresponding to typic...
متن کاملMany-body effects on intersubband resonances in narrow InAs/A1Sb quantum wells
Intersubband polarization couples to collective excitations of the interacting electron gas confined in a semiconductor quantum well (QW) structure. Such excitations include correlated pair excitations (repellons) and intersubband plasmons (ISPs). The oscillator strength of intersubband resonances (ISBRs) strongly varies with QW parameters and electron density because of this coupling. Using th...
