We report on random lasing observed with 5-m-long Er-doped fiber comprising an array of
weak fiber Bragg gratings (FBGs) inscribed in the fiber core and uniformly distributed over …

The review covers current achievements and prospects for the development of fiber
sensorics associated with tilted fiber Bragg gratings (TFBGs), including metal-coated …

Silica-based optical fibers with an ultra-high Yb concentration were systematically studied.
Three the most commonly used in industry glass matrixes for active fiber core were …

The paper presents a novel multi-pass point-by-point method for high-precision inscription of
