Abstract:
A multi-material structure comprising:a first component of a first material through which light is propagated, the first component having an end surface; a second component of a second material different from the first material through which light is propagated, the second component having an end surface, the second component end surface adjacent to the first component end surface; and wherein the first component end surface is at an angle other than normal to the direction of light propagation through the first component, the second component end surface is at an angle other than normal to the direction of light propagation through the second component; and the angles are such as to reduce reflection loss for the light polarization direction which has a higher propagation loss in the second component than another polarization direction wherein PDL is less than if the first and second component end surfaces are normal to the direction of light propagation.
