The fabrication method and application of solid-core photonic crystal fiber and air-core photonic bandgap fiber grating are studied.Long-period fiber grating is written into solid photonic crystal fiber and its high-sensitivity strain sensor is developed.Through focused CO2 laser on photonic crystal fiber Surface notch method developed optical fiber type polarizer.Using CO2 laser periodically collapse air holes in the air core photonic bandgap fiber write novel long period fiber grating by using an excimer laser or femtosecond laser by double Beam Interference Theory A fiber Bragg grating is written in a fine core germanium-doped photonic crystal fiber or a fine core pure silicon photonic crystal fiber.
