Abstract :
Thin layers of strongly absorbing chalcogenide glasses is investigated. The characteristic lengths of long range surface polariton (LRSPs) in terms of the propagation length and the confinement to the thin film is discussed. Similar propagation lengths and mode confinements are found at optical frequencies for LRSPs in films of chalcogenide glasses and for long range surface plasmon polaritons in gold. This characteristic makes chalcogenide glasses an interesting alternative to metals for several plasmonic applications.
