Surface phonon polaritons for infrared optoelectronics

Infrared surface polaritons on antimony.

The semimetal antimony, with a plasma frequency ~80 times less than that of gold, is potentially useful as a host for infrared surface polaritons (SPs). Relevant IR SP properties, including the frequency-dependent propagation length and penetration depths for fields into the media on either side of the interface, were determined from optical constants measured on optically-thick thermally-evapo...

Theory of Nonlinear s-Polarized Phonon-Polaritons in Multilayered Structures

A theory is presented for the dispersion relations of the nonlinear phonon-polaritons arising when phonons are coupled to the electromagnetic waves in multilayered structures of nonlinear materials. The calculations are applied to a multilayered structure consisting of a thin film surrounded by semi-infinite bounding media where each layer may have a frequency dependent dielectric function and ...

Mid- and far-infrared optical characterization of monoclinic HfO2 nanoparticles and evidence of localized surface phonon polaritons

Monoclinic HfO2 nanoparticles (9 45 nm) are synthesized using a sol-gel method and optically characterized using transmissionand angle-dependent reflection spectroscopy in the midto far-infrared. A detailed HfO2 identification of the infrared-active phonon modes is presented; consistent with previously reported thin film values, and in excellent agreement with density functional perturbation th...
