“…Superposed to the bright circle associated with the leakage of BSW-coupled fluorescence, the BFP fluorescence image reveals two additional (polychromatic) bright arcs, mutually intersecting in the center. A similar result has been found for SPCE on periodically corrugated metallic films [21][22][23] and has been explained as a signature of the diffraction of plasmoncoupled fluorescence. In fact, when the grating vector equals the wavevector of the surface mode wherein the emission is coupled, a normal diffraction may occur normally to the sample surface.…”

“…11 The photons used to excite SPPs in that experiment were emitted by a true source of temporally spaced photons based on the spontaneous parametric downconversion (SPDC) phenomena. 22,23 Working toward SPP quantumstate tomography, we explore the quantum limit of SPP tomography, [24][25][26][27][28][29][30] also called the leakage radiation microscopy, 19-21 using a combination of two well established and understood methods: the single SPP excitation method used in Ref. 11, and the method for detection of photons coupled to SPPs used in Ref.…”

“…29,30 Classical SPP tomography allows for the direct observation of SPP Bloch function 27,28 and equifrequency curve dispersion 25,26 in plasmonic crystals where the surface waves are excited in leaky modes. In SPP tomography, the photons used for imaging are the ones that leak to the sample substrate regardless of the measurement process.…”

We report the direct excitation and detection of single-photon surface plasmon polariton (SPP) using a SPP tomography arrangement. Temporally spaced photons produced by spontaneous parametric downconversion were used to excite single-photon SPPs. The quantum statistics of the leakage radiation was studied using a Hanbury-Brown & Twiss correlator arrangement. We observed a violation of the second order coherence test indicating leakage of temporally spaced photons. This demonstrates that leakage radiation associated with SPPs excited by single photons is composed of temporally spaced photons. Reaching the quantum regime of SPP tomography opens the door for further advances in SPP quantum state determination using SPP tomography.

“…21,22 Leakage radiation microscopy (LRM) is used to detect the emitting angles of the optical modes-coupled fluorescence which correspond to the resonant dips (or angles) on the Figure 2(a). [23][24][25] A polarizer is placed before the CCD camera to determine the polarization state of the emitting fluorescence, which can also determine the polarization of the polymer loaded optical modes on the 1DPC. A band pass filter with center wavelength at 600 nm is used to allow only fluorescence at this wavelength to reach the CCD camera.…”

We numerically and experimentally demonstrate that a polymer film-coated one-dimensional photonic crystal (1DPC) can sustain transverse electric (TE) polarized modes without the limit of guided layer's thickness. Our results indicate that two propagating modes are existing inside the polymer film, the first one is the TE polarized Bloch surface wave, and the second one is the TE polarized guided mode. Here in, the evolution of these two modes with change in the polymer film thickness is presented. Our numerical simulation results are in well-agreement with the experimental data obtained using back focal plane imaging. V C 2014 AIP Publishing LLC. Optical waveguides are physical structures that guide electromagnetic waves in the optical spectrum. These structures are used as components in integrated optical circuits, as the long distance transmission medium in light wave communications, or for biomedical imaging. Dielectric optical waveguides play a crucial role in the present-day optoelectronics industry. The usual dielectric waveguide cannot restrict the spatial localization of the optical energy beyond the k 0 /2n limit, where the k 0 is the free space photon wavelength and n is the refractive index of the waveguide.1 For this reason, surface plasmon polaritons (SPPs) based waveguides on metallic-dielectric or metallic structures provide a good solution to this problem, due to the shorter wavelength of the SPPs than the photon wavelength at the same frequency.2-4 However, the propagating loss of the SPPs waveguide is very large due to the absorption and scattering by the metallic structures.5 Recently, the polymeric nano-ridges on a one-dimensional photonic crystal (1DPC), made of all dielectric materials, were found to guide optical waves with nano-scale spatial localization and much smaller propagation loss. 6,7 For this kind of 1DPC, Bloch Surface Waves (BSWs) are generated which guide the electromagnetic waves along the interface between the 1DPC and the upper air-space. 8,9 The BSWs are dielectric analogs to the SPPs whose properties are also sensitive to the surrounding medium. [10][11][12][13][14][15][16] In this Letter, we numerically and experimentally investigated the optical properties of the BSWs in the presence and absence of various thicknesses of polymer layer on the upper surface of the 1DPC. The polymer film coated 1DPC can be assumed as an asymmetric planar waveguide, and the polymer film itself can be treated as the guided layer. Our results verify that the guided electromagnetic field becomes more confined with the inclusion of the polymer film even if the thickness of the polymer film is much smaller than the wavelength of the incident light. In other words, for this kind of asymmetric planar waveguide, there is no cut-off thickness of the guided layer, which is certainly favorable for the miniaturization of optoelectronic components down to nanometer scales. The evolution of the optical modes inside the polymer film coated 1DPC is demonstrated theoretically and experimentally.
