Polymer microfabrication applied to assembly and connection problems

This paper will describe the wide range of polymer microfabrication techniques that are now available not only for moulding channels (and surface reliefs in general) but also for filling the reliefs with the range of materials required to produce microsystems. Examples will be described in which a polymer surface relief has been used to provide an application function, for example, a diffraction grating or a channel waveguide and where the the problems of optical interconnection and assembly have been addressed
