    Invited talk

    Thermal waves generated by the periodic fluctuations on time of a temperature field are widely used to determine thermal properties of macro-, micro-, and nanomaterials via standard photothermal techniques (thermoreflectance, radiometry, 3w, photoacoustics, and resonant cavity), and they usually do not carry a net heat flux in materials with constant thermal properties. By contrast, in...

  2. 194. ZnSe-based solar-blind ultraviolet photodetectors with hybrid Ag-nanowire and Ni/Au contacts (S07-OP-101)

    Oral presentation (virtual)

    Zinc selenide is a wide bandgap semiconductor which is attractive for the fabrication of many optoelectronic devices, including ultraviolet (UV) photodetectors, due to its large bandgap energy (2.67 eV at 300 K), high electric breakdown field strength (~ 1 MV/cm), as well as high resistance to intense UV and X-ray radiation. Most commercial UV-photodetectors are based on Si or GaAs...

  3. 44. The Gouy phase of long-range Gauss-Bessel beams (S07-OP-100)

    Oral presentation

    One of the processes that is assumed to be well understood, is that any fundamental Gaussian light beam experiences an axial phase shift of $π$ radians with respect of a reference plane wave when passing through its focus. For a higher-order Hermite-Gaussian mode with mode indices ($m,n$) this phase is multiplied by a factor of ($1+m+n$). For a higher-order Laguerre-Gaussian mode with mode...
