Development of the writing techniques of the fiber Bragg gratings during the optical fiber drawing process

In this area, the writing techniques are developed for the Bragg gratings (of a type I) formation during the drawing of the birefringent optical fiber carrying an elliptical strained cladding.

Technology of the grating arrays formation within optical fiber during the drawing process (the gratings maintaining the radiation polarization) may simplify and reduce the price creation of the sensitive elements of the phase interferometric sensors.
