All-polymer based fabrication process for an all-polymer flexible and parallel optical interconnect

摘要: We proposed and demonstrated a new all-polymer based fabrication process for an flexible parallel optical interconnect cable in which vertical light coupler is integrated. The approach potentially cut down the cost by eliminating metallization alignment of multiple masks. Throughout we used polyimide as the substrate, coated by Epoclad claddings, then AP2210B WPR 5100 were to fabricate waveguides 45 degree mirror couplers, respectively. In addition, precisely aligned couplers are achieved using polymer-based, non-metallic, transparent phase-based marks. tested feature specific phase-based alignment system. shape depth marks optimized phase contrast and Schlieren imaging. Our results shows that contrast image enhanced compared observed a conventional imaging Such enables integrate polymer only using polymer based on layer.
