Abstract
We report on the fabrication of a flexible optical interconnection module that has been incorporated as a part of an optical printed circuit board (O-PCB). Optical waveguide arrays are fabricated on flexible polyethylen terephthalate (PET) substrate by UV embossing technology. Electrical layers carrying vertical cavity surface emitted laserdiode (VCSEL) and photodiode (PD) array are attached to the optical layer. We measured optical losses of the flexible waveguide arrays bent over various curvatures and characterized transmission performances of the flexible optical PCB (FO-PCB) module. FO-PCB performed high speed optical interconnection between chips over four waveguide channels up to 7.5Gbps on each.
