WAFT Series

Product catalog summary

Overview
The Edge-Coupling Waveguide Array to Fiber Transposer (EC-WAFT) is a crucial interface for edge coupling configurations in photonic integrated circuits (PICs). It integrates a spot size converter and waveguide pitch matching to ensure seamless coupling with various I/O configurations. The ioNext platform offers a range of EC-WAFT products with customizable port numbers, output pitch, and mode size.
