1. A method comprising:

  • (a) providing a phosphorus-containing polymer of the general formula I or II,
    P(A)m(F)n1(U)o1



    (I)
    P(A)m(UFn2)o2



    (II)wherein P represents a linear or branched, uncrosslinked or crosslinked, homo- or heteropolymeric polymer component, A represents identical or different phosphorus-containing groups bonded to P, m represents a number from 3 to 1000, F represents identical or different functional groups bonded directly or indirectly to P which are present in addition to A, n1 represents a number from 1 to 1000, n2 represents a number from 1 to 100, U represents identical or different, linear or branched, uncrosslinked or crosslinked oligomeric or polymeric segments made up of identical or different monomers, which are bonded to P, o1 represents a number from 0 to 1000, and o2 represents a number from 1 to 1000;

    (b) applying the polymer to a dielectric waveguide so as to form a coating on the dielectric waveguide; and

    (c) forming an optical signal transducer comprising the coated dielectric waveguide.
