Abstract
The invention includes a multi-material structure comprising at least two components through which light is propagated. At least two structure components are of different materials and are joined to one another at an end surface of each either directly or indirectly. The end surfaces are at angles other than normal to the direction of light propagation. The multi-material structure has a polarization dependent loss less than if the components had end surfaces normal to the direction of light propagation. Embodiments of the invention are particularly applicable to a waveguide substrate/fiber capillary interface. Also included is a method of reducing polarization dependent loss between joined components through which light is propagated.
