1200-1600nm Long Period Fiber Grating
       1200-1600nm Long-period fiber grating is a kind of fiber grating based on the coupling between the fundamental mode 
of the core and the cladding mode transmited in the same direction, it features low reflectivity, wide band, high sensitivity of 
refractive index change, it's widely used in EDFA Gain Flat, Fiber Optic Sensor system, the parameters can be customized.
