Direct Optical Wiring (DOW)
Today’s data centers are struggling to cope with increasing demands for artificial intelligence (AI), machine learning (ML) workloads or 5G/6G applications, defense and security.
The disruptive innovation of direct optical wiring (DOW) in integrated optical interconnects will drive the future of high-performance computing.
Direct Optical Wiring (DOW) Technology
Lessengers’ Direct Optical Wiring (DOW) technology enables next-generation optical interconnects through ultra-precise, freeform optical waveguide fabrication. The diameter of polymer optical wires can be precisely controlled over a wide range—from 0.2 μm to several hundred micrometers—allowing flexible and application-specific optical routing. DOW achieves sub-micron (< 1 μm) positioning accuracy, currently limited only by the resolution of optical microscopy. Designed as an air-cladded optical waveguide, DOW provides strong optical confinement and low propagation loss, making it an ideal foundation for high-density, high-performance optical integration.
