Abstract
Experimental measurements of laterally tapered multimode waveguide bends fabricated photolithographically on FR4 printed circuit board establishes that the product of the mean insertion loss (in linear units) and the mean source misalignment tolerance is a constant which depends only on the taper ratio, TR (input width/output width) and not on the radius of curvature, R. The minimum loss of 0.78 dB occurs in the special case of TR=0.8, R=14 mm. Together these form waveguide layout design rules for board-to-board and chip-to-chip optical interconnects.
