A method of forming a waveguide is disclosed, as well as the waveguide it self. A multilayer stack of light guiding layers is formed, and the multilay er stack is delaminated between light guiding layers to form a waveguide bet ween the light guiding layers. The multilayer stack is delaminated in a patt erned region between light guiding layers. Here a new approach is described, wherein hollow microchannels forming a Bragg waveguide assembly are fabrica ted by controlled formation of thin film delamination buckles within a multi layer stack. A hollow waveguide is formed by alternating layers of the multi layer stack forming light guiding surfaces. The hollow waveguide is formed b etween layers that delaminate from each other, as for example under applied stress to one or more of the layers. The multi-layer stack may be formed of alternating layers of low and high index of refraction materials, as for exa mple forming omni-directional dielectric reflectors. Metal cladding of the w aveguiding layers is also provided in one embodiment, as for example by prov iding a metal base layer and a cap layer. Methods of assembly are disclosed, as well as the assemblies themselves.
