Georgia Institute of Technology researchers experimentally validated photonic waveguide bends with 2.3-micrometer radii, meeting commercial foundry fabrication rules.

Georgia Institute of Technology researchers published an experimentally validated method for compact photonic waveguide bends. The reported bend radius is 2.3 micrometers; this is a physical device dimension, not a semiconductor process-node designation.

The work explicitly addresses compatibility with commercial foundry processes. The paper’s title, “Low-loss ultra-compact photonic bends with enhanced fabrication tolerance for commercial foundry processes,” identifies both optical loss and fabrication tolerance as design objectives.

The supplied summary reports experimental validation but does not quantify the optical-loss improvement. It also provides no named foundry, manufacturing yield, wavelength range, or system-level performance result, limiting the analysis to the demonstrated bend geometry and stated fabrication compatibility.
