The expanding mid-infrared (MIR) photonics market faces a significant challenge due to the lack of durable MIR optical fibers. Here, the authors fabricate gallate glasses with tantalum oxide, achieving enhanced water corrosion resistance and nonlinear refractive index, paving the way for robust long-length optical fibers, and advancing fiber-based MIR technologies.
