摘要：
Long period fiber grating devices are finding a broad range of applications as wavelength selective filters and spectrally selective sensors. In this paper I describe the theory and fabrication of long period fiber gratings, including mask considerations for UV fabrication, and give an overview of applications. Two applications are described in detail: an embeddable point sensor for strain and temperature in a structure, and an all-fiber, coupler-free Mach-Zehnder interferometer for WDM filtering applications.
