“…Control of the photon absorption, scattering, and localization in an absorbing medium is a current research topic and is important for a variety of fundamental studies and practical applications [1][2][3][4][5]. Recent studies show that coherent perfect photon absorption can be realized in linear dielectrics confined in a Fabry-Perot structure [6][7][8][9][10][11].…”

It has been shown that perfect photon absorption can occur in the linear excitation regime of cavity quantum electrodynamics (CQED), in which photons from two identical light fields coupled into two ends of the cavity are completely absorbed and result in excitation of the polariton state of the CQED system. The output light from the cavity is totally suppressed by the destructive interference and the polariton state can only decay incoherently back to the ground state. Here we analyze the perfect photon absorption and onset of optical bistability in the nonlinear regime of the CQED and show that the perfect photon absorption persists in the nonlinear regime of the CQED below the threshold of the optical bistability. Therefore the perfect photon absorption is a phenomenon that can be observed in both linear and nonlinear regimes of CQED. Furthermore, our study reveals for the first time that the optical bistability is influenced by the input-light interference and can be manipulated by varying the relative phase of the two input fields.

“…Nonlinear plasmonics brings the functionality of nonlinear optics, including wavelength conversion and switching, to the nanoscale [1][2][3][4][5][6]. The goal is to obtain efficient light energy conversion or optical functionality at the subwavelength scale [7][8][9][10][11][12][13][14][15][16]. This is in contrast to conventional nonlinear optics, which typically requires phase matching over long distances or microcavities to obtain high conversion efficiency [17][18][19][20][21].…”

We measure third harmonic generation (THG) as a function of infrared fundamental wavelength for gold nanoparticles over a gold film. An order of magnitude enhancement in THG is found at ~2.5 eV. We ensure that this enhancement is away from plasmonic resonances, so that it may be attributed directly to the ultrafast third-order susceptibility of gold. Using a simple relation between linear and third-order susceptibilities in conjunction with the linear response of gold, we show that the experimental results agree well with the enhancement from interband transitions. This result is interesting for potential applications leveraging telecom-band sources, such as third harmonic deep-tissue imaging with plasmonic nanoparticle markers.

“…Photon confinement and trapping is a current research topic and is important for a variety of fundamental studies and practical applications [1][2][3][4]. Considerable research efforts have been spent in exploring new ideas and developing practical techniques to slow down, localize, trap, and store photons in atomic media or photonic structures [1][2][3][4][5][6][7]. A well-know example is the Anderson localization in which light can be trapped in a disordered medium through multiple light scatterings [2][3].…”

We propose and analyze a scheme for photon trapping in an optical resonator coupled with two-level atoms. We show that when the cavity is excited by two identical light fields from two ends of the cavity respectively, the output light from the cavity is suppressed while the intra-cavity light field is near the maximum due to the excitation of the polariton state of the coupled cavity and atom system. We also present methods for the direct probing of the trapped polariton state. The photon trapping is manifested by the destructive interference of the transmitted light and the incident light. Such photon trapping is quite generic and should be observable experimentally in a variety of cavity quantum electrodynamics systems.
