Spectral and Microscopic Behavior of Type III Femtosecond Fiber Bragg Gratings at High Temperatures
Fiber Bragg gratings are key components for optical fiber sensing applications in harsh environments. Microvoids, or so-called type III fiber Bragg gratings, fabricated using femtosecond lasers and the point-by-point technique, were characterized at high temperatures (>1100 °C). For this purpose,...
