Zusammenfassung:	The present disclosure relates to systems and methods of making polymeric optical layers for optical layering applications. In an aspect, a waveguide device for a head mounted display is provided. The waveguide device may include a waveguide die having a first refractive index range and a polymeric optical layer. The polymeric optical layer may include a second refractive index range that is different from the first refractive index range and a thiol-containing polymer. For example, the thiol-containing polymer may include thiourethane. In some embodiments, the thiol-containing polymer may be formed from a monomer mixture including a thiol-containing compound and an isocyanate. For example, the thiol-containing compound may include 4-mercaptomethyl-3,6-dithia-1,8-octanedithiol (MDTODT) and/or the isocyanate may include m-xylylene diisocyanate (XDI). In some embodiments, the monomer mixture may include a second thiol-containing compound, such as, for example, 1,3-benzene dithiol (1,3-BDT).
