| 摘要 |
A planarized signal communications system (110) embedded within a printed circuit board (102) is disclosed, comprising first (118) and second (120) index buffer layers within the printed circuit board, a polymer waveguide (116) disposed below the first and above the second index buffer layers, an electrical-to-optical transmitter (122) disposed within the first index buffer layer in direct adjoinment with the polymer waveguide, a reflective element (126) disposed within the polymer waveguide in direct alignment with the electrical-to-optical transmitter and adapted to reflect optical energy from the electrical-to-optical transmitter along the polymer waveguide, an optical-to-electrical receiver (124) disposed within the first index buffer layer and in direct adjoinment with the polymer waveguide, a reflective element (126) disposed within the polymer waveguide in direct alignment with the optical-to-electrical receiver.
