Long period fiber bragg grating (LPFG) is formed by the periodic refractive index modulation in the fiber axis, and its period is generally larger than 100µm. Its coupling mechanism is: the fundamental mode of the fiber core transmitted forward is coupled into the cladding mode of the forward transmission of several specific wavelengths, and the cladding mode is quickly lost, so the LPFG basically has no retroreflection, and in its transmission there are several absorption peaks at specific wavelengths in the spectrum. Features Of long period fiber grating No Reflection Type Low Insertion Loss Application Of long period grating Notch Band Filter GFF for EDFA Optical Fiber Sensing There are many fiber optic sensing companies, but we are one of the best choices for you. https://www.atgrating.com/products/long-period-fbg.html
