On-line Inscribing Ultra-weak Fiber Bragg Grating Arrays in UV-transparent Coating Optical Fiber

We propose a novel method for fabrication of ultra-weak Fiber Bragg Grating (UWFBG) Arrays, which grating array is UV-inscribed with single exposure pulses in the UV-Transparent Coating Optical Fiber (UV-TCF) assisted by a fiber winding system. Compared with the drawing tower grating technique, such system has a more flexible grating control, such as wavelength multiplexing, space distribution.
