Thin glass based electrical-optical circuit boards (EOCB) using ion-exchange technology for graded-index multimode waveguides

Abstract: The concept and experimental results to manufacture electrical-optical circuit boards (EOCB) with buried optical waveguides using thin-glass sheets (display glass) are presented. An ion-exchange process was developed to manufacture the graded index waveguides in thin-glass sheets. Besides of their excellent optical properties no mechanical structuring is necessary for the waveguides. Their properties were simulated and experimentally validated. The circuit board assembly is presented, as well as the concept de… Show more

“…As published in [26] electrical optical circuits boards (EOCB) with thin glass layers are perfectly matched to the kind of transceiver modules introduced in that paper. For that reason the optical plane of the transceiver has to be on the same level as the optical layer in the EOCB.…”

“…Glass is significantly more stable than polymer materials and withstands the thermal load of lamination. The lamination of a glass waveguide layer into a PCB is proven [6]. Furthermore glass is an excellent electrical substrate material for interposer applications [7].…”

“…Board level polymer multimode waveguides are widely used in the wavelength range of 850nm but lacking of high propagation loss in the telecom wavelength range. Glass waveguides implemented by ion exchange can be processed as single-and multimodewaveguides having low loss at 850, 1310 or 1550 nm [6]. For post processing in particular for laminating a glass waveguide layer into a printed circuit board (PCB) requires temperatures up to180°C and adequate amount of load.…”

“…Griese, Franke, Happel, etc discussed the optical mechanism of optical waveguide, light steering device of embedded optical waveguide in board level circuit, and optical fiber interconnection between circuit boards. Fraunhofer IZM [5] also joined the research on photoelectric interconnection together with Siemens. Krabe, Schroder, Brusberg, etc discussed photoelectric circuit board, fabrication of waveguide and embedded single mode waveguide in circuit board.…”
