Photolithographically manufactured acrylate multimode optical waveguide translation and rotation misalignment tolerances

This paper reports numerous experimental measurements and modelling result of the loss caused by various amounts of translation and rotation misalignment in the optical backplane system. Combinations of VCSEL as the light source and waveguides of various widths have been input in the system. The source has been moved away from the centre of a channel waveguide in the horizontal and vertical direction gradually to find out the translation and rotation tolerance. Offsets between VCSEL-waveguide and waveguide-receiver have been studied to find the translation and rotation tolerance.
