Taking typical fiber grating structures as an example, long period gratings (LPGs) are inscribed on the fiber surface, making them more suitable for direct RI sensing.
As typical grating type of sensor, long period fiber grating (LPFG) has higher curvature sensitivity than that of FBG due to its special coupling mechanism between core mode and cladding
Long period grating has a wide variety of applications, including band-rejection filters, gain flattening filter and sensors. Various gratings with complex structures have been designed: gratings combining
