Three dimensional optical interconnect on organic circuit board

We propose high speed optical interconnection which is three dimensional optical lanes using polymer materials fabricated on an organic circuit board with metal lines and pads. These optical lanes transmit optical signals not only on a plane surface but into the other side of a circuit board. It has following three particular portions; (1) curved parallel optical waveguide; (2) 45 degree reflection mirror; (3) optical via hole. Four channel three dimensional optical lanes with current electrical lines and pads are newly developed on the organic circuit board named CPCoretrade. We characterize the optical lanes by transmission loss and passed through eye diagram, and optical signal transmission is confirmed. Then optical signal transmission up to 3Gbps/channel are demonstrated with 850nm VCSEL flip-attached on the circuit board with active and passive electronic devices and components as driving circuit
