Abstract

Disclosed is an optical waveguide component having a layered structure comprising a polymeric guiding layer sandwiched between two deflection layers of lower refractive index than the guiding layer, in which the guiding layer polymer comprises moieties susceptible to a change of refractive index when subjected to appropriate irradiation. Thus, the guiding layer polymer is rendered photobleachable. According to the invention, themoieties include a structure that satisfies the following chemical formula: in which n is 0,1 or 2, and R1 and R2 may be the same or different, and represent hydrogen, a C1-6 alkyl group, notably a methyl, ethyl, or propyl group, or a functional group through which the polymer can be crosslinked, such as isocyanate, hydroxy, epoxy. It has been found that these structures lead to unexpectedly favourable bleaching characteristics.
