In this paper, we describe experimental and modeling results that illucidate the nature of coupling between surface plasmon polaritons in a thin silver film with the molecular resonance of a zinc phthalocyanine dye film. This coupling leads to several phenomena not generally observed when plasmons are coupled to transparent materials. The increased absorption coefficient near a molecular resona...

Laboratory measurements of the absorption coefficient and refractive index of solid CO2 are reviewed for all parts of the electromagnetic spectrum from the ultraviolet to the microwave with emphasis on values for temperatures above 77 K. The available measurements in some cases require reinterpretation. A compilation of the spectral absorption coefficient kabs is made for 52-nm to 160-nm wavele...

The conditions under which light interference in a transparent quarter-wave layer of refractive index n1 on a transparent substrate of refractive index n2 leads to 50% reflectance for incident unpolarized light at an angle phi are determined. Two distinct solution branches are obtained that correspond to light reflection above and below the polarizing angle, phi(p), of zero reflection for p pol...

Near-zero-index platforms arise as a new opportunity for light manipulation with boosting of optical nonlinearities, transmission properties in waveguides, and constant phase distribution. In addition, they represent solution to impedance mismatch faced photonic circuitry offering several applications quantum photonics, communication, sensing. However, their realization is limited the availabil...

Refractive index (RI) is a complex number comprising a real refractive index and an imaginary part: the absorption (or extinction) coefficient. The analysis of refractive index by the Surfoptic Imaging Reflectometer yields an approximation to the real part of the refractive index. The well established technique of ellipsometry, by contrast, can determine both the real refractive index and the e...
