Abstract
For coupling of light into and out of the optical layer in electric-optical printed circuit boards (PCBs) a scheme for a perpendicular coupling of the light with respect to the waveguide layer is presented. The required 90° light deflection is accomplished by integrated silver-coated 45° micro mirrors which are moulded into polymer substrate together with the waveguide grooves. Exact alignment of the optoelectronic modules with respect to the mirrors is obtained by holes in the waveguide layer and MT pins in the OE-modules.© (2003) COPYRIGHT SPIE--The International Society for Optical Engineering.
