AbstractLong-period gratings were written in nitrogen-doped-silica-core optical fibers by point heating. The periodic variations of the effective refractive index were induced via diffusion of nitrogen from the fiber core. It is shown experimentally that such gratings remain functional at temperatures of up to 1200 °C.
