Sol–gel chirowaveguides investigated via MLine technique

摘要: Abstract Chirowaveguides, planar waveguides with a chiral core, are made of organo-modified silane sol–gel material. The losses, optical rotation (OR), absorption spectra and circular dicroism (CD) measured discussed. activity for the organic molecule 1,1′-binaphtyl-2,2′-dyil hydrogen phosphate is preserved in solid thin films. specific OR film material 11°/mm at λ  = 488 nm. It shown that prism coupling, known as m -line technique, not appropriated to put into evidence polarization feature chirowaveguides.
