ABSTRACT
We demonstrate experimentally that strongly absorbing chalcogenide thin films can support long range surface polaritons. Moreover, the possibility to change the phase of this material allows us to investigate the influence of the permittivity of the thin film on the surface modes. We demonstrate the relative insensitivity of these modes to the permittivity of the thin film. Extending the range of materials that support long range surface polaritons to strongly absorbing layers opens new possibilities for applications that were thought to be limited to weakly absorbing media.

    We report on the first observation of the thickness-dependent photoluminescence-decay time of exciton-exciton scattering in ZnO thin films, which indicates the slower propagation of photon-like polaritons compared to that in bulk by two orders magnitude.

    In this work, we present an observation of laser induced periodic surface structures (LIPSS) on graphene. LIPSS on other materials have been observed for nearly 50 years, but until now, not on graphene. Our findings for LIPSS on multi-layer graphene were consistent with previous reports of LIPSS...

    We investigate near-field thermal radiation between a nanometric film and a bulk SiC using fluctuational electrodynamics. Results show a narrow spectral band enhancement of the radiative flux for nanometric emitters due to coupling of surface phonon polaritons inside the film. For a 10 nm thick...

    Terahertz phonon-polariton generation and real-space imaging with femtosecond optical pulses are demonstrated in a 10-μm-thick film of single-crystalline lithium niobate that was generated through crystal ion slicing. The film dispersion properties were characterized throughout the polariton...

    The conductive ZnO films deposited using atomic layer deposition (ALD) on the optical glass substrates were studied using the modified method of the disturbed total internal reflection within the range 400...1400 cm-1 for the first time.

    We report on buried planar waveguides in a highly nonlinear infrared transmitting chalcogenide glass, fabricated using a combination of inverted deposition of the molten glass phase and high-velocity spinning.

    We have prepared twelve Ge-As-Se chalcogenide glass films with different chemical compositions and investigated their stability to exposure with near bandedge light. The evolution of two key parameters, the refractive index at 1550 nm and the bandgap with increasing fluence were fitted with...

    The dynamics of the entanglement for a solid polariton system is investigated. The polariton system is a photon-phonon complex and its time-dependent characteristic function in the Wigner representation for the system is obtained analytically. It is found that when the photon field is initially...
