Description:
Chiral gratings with double helix symmetry were produced by twisting glass optical fiber with a noncircular core cross section as it passed through a miniature oven. We observed polarization-selective transmission in chiral fibers with pitches of tens of micrometers. Two modes of optical interaction were differentiated. In chirallong-period gratings, dips in transmission were observed at wavelengths associated with scattering into distinct cladding modes mediated by the chiral grating. In chiral intermediateperiod gratings, a broad scattering band was observed. These gratings can be used to produce sharp or broad polarization-selective filters.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kopp, Victor I -- Churikov, Victor M -- Singer, Jonathan -- Chao, Norman -- Neugroschl, Daniel -- Genack, Azriel Z -- New York, N.Y. -- Science. 2004 Jul 2;305(5680):74-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Chiral Photonics, Inc., Clifton, NJ 07012, USA. vickopp@chiralphotonics.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15232101" target="_blank"〉PubMed〈/a〉
