“…On the basis of the versatility of the described antenna structure and its unprecedented ability to produce high-directivity, electrically controllable, optical beams in one or more desired directions, we anticipate a myriad of practical and fundamental applications in optical spectroscopy, sensing, quantum optics (for example, novel single photon sources), analytical chemistry, medicine, non-linear optics, solid-state light emitters, perhaps even nanolasers [36][37][38][39] , and optoelectronics.…”

nanometallic optical antennas are rapidly gaining popularity in applications that require exquisite control over light concentration and emission processes. The search is on for highperformance antennas that offer facile integration on chips. Here we demonstrate a new, easily fabricated optical antenna design that achieves an unprecedented level of control over fluorescent emission by combining concepts from plasmonics, radiative decay engineering and optical beaming. The antenna consists of a nanoscale plasmonic cavity filled with quantum dots coupled to a miniature grating structure that can be engineered to produce one or more highly collimated beams. Electromagnetic simulations and confocal microscopy were used to visualize the beaming process. The metals defining the plasmonic cavity can be utilized to electrically control the emission intensity and wavelength. These findings facilitate the realization of a new class of active optical antennas for use in new optical sources and a wide range of nanoscale optical spectroscopy applications.

“…The existence of the decoherent mechanism can make the energy exchange between the atoms and the magnetic field weaker until it disappears. Nowadays, researchers seek a variety of ways to reduce the influence of cavity EM such as reducing the volume [99], coating [100], and superconductivity of cavity [101] to increase the coherence interaction intensity. When this coherent mechanism is dominated rather than the decoherent mechanism, we usually called it the strong coupling.…”

Exciton-plasmon coupling interactions: from principle to applications

Abstract:The interaction of exciton-plasmon coupling and the conversion of exciton-plasmon-photon have been widely investigated experimentally and theoretically. In this review, we introduce the exciton-plasmon interaction from basic principle to applications. There are two kinds of exciton-plasmon coupling, which demonstrate different optical properties. The strong exciton-plasmon coupling results in two new mixed states of light and matter separated energetically by a Rabi splitting that exhibits a characteristic anticrossing behavior of the exciton-LSP energy tuning. Compared to strong coupling, such as surface-enhanced Raman scattering, surface plasmon (SP)-enhanced absorption, enhanced fluorescence, or fluorescence quenching, there is no perturbation between wave functions; the interaction here is called the weak coupling. SP resonance (SPR) arises from the collective oscillation induced by the electromagnetic field of light and can be used for investigating the interaction between light and matter beyond the diffraction limit. The study on the interaction between SPR and exaction has drawn wide attention since its discovery not only due to its contribution in deepening and broadening the understanding of SPR but also its contribution to its application in light-emitting diodes, solar cells, low threshold laser, biomedical detection, quantum information processing, and so on.

“…41 This is mainly due to the much higher spontaneous emission β factor, spatial gain overlap factor, and Purcell factor of deeply confined plasmon cavity modes compared to that of diffraction limited cavity modes. 18,20,21,42 The WEB plasmon laser can also achieve unidirectional out coupling by cutting off one out coupling waveguide. Providing the cut is made at the silver nanowire edge, the corresponding cavity boundary would become total internal reflective.…”

With unprecedented ability to localize electromagnetic field in time and space, the nanometer scale laser promises exceptionally broad scientific and technological innovation. However, as the laser cavity becomes subwavelength, the diffraction of light prohibits the directional emission, so-called the directionality, one of the fundamental attributes of the laser. Here, we have demonstrated a deep subwavelength waveguide embedded (WEB) plasmon laser that directs more than 70% of its radiation into an embedded semiconductor nanobelt waveguide with dramatically enhanced radiation efficiency. The unique configuration of WEB plasmon laser naturally integrates photonic and electronic functionality allowing both efficient electrical modulation and wavelength multiplexing. We have demonstrated a plasmonic circuit integrating five independently modulated multicolored plasmon laser sources multiplexed onto a single semiconductor nanobelt waveguide, illustrating the potential of plasmon lasers for large scale, ultradense photonic integration. KEYWORDS: Surface plasmon, laser, spaser, circuit, multiplexing and modulation R egarded as the key driver of ultradense optoelectronic circuitry, single-molecule sensing, ultrahigh-density data storage, nanoscale lasers have attracted much attention. 1−7 The research of nanoscale lasers is rapidly advancing, and a variety of approaches have been explored including Fabry−Peŕot lasers, 8−10 whispering gallery lasers, 11−13 photonic crystal lasers, 14−17 and metallic lasers. 18−26 Recently, plasmon lasers with both a physical size and an optical mode confinement below the diffraction limit of light in a different number of dimensions have been demonstrated 19−21,24−26 using localized surface plasmons bound to metal surfaces. 27−31 With the unprecedented ability to generate intense electromagnetic radiation at the nanoscale in femtosecond time scales, plasmon lasers now stimulates the exploration of exceptionally broad scientific and technological innovation at the nanometer scale. However, critical challenges remain and must be tackled before these plasmon lasers can be utilized as integrated light sources. First, the large momentum mismatch of light inside and outside of a deep subwavelength plasmon cavity results in diffraction into all directions, inhibiting directional emission and efficient collection of optical power from a plasmon laser for practical applications. Furthermore, due to the intrinsic metal Ohmic loss limited quality factor, the radiation efficiency of plasmon laser is very low. The devices deliver energy to the nanoscale plasmonic mode but just release only a small part of their optical energy to the far field before it is dissipated in the metal. Last, scaling down integrated photonics requires multiplexed nanolasers with direct on-chip electrical modulation, which places constraints on the integration of driving electronics without disturbing the cavity mode or increasing the device footprint.Here, we demonstrate an integrated waveguide embedded (WEB) ...
