文摘Using only one optic element,the phase mask provides a robust and inherently stable methodfor reproducing fiber Bra gg gratings,and reduces the complexity of the fiber grating fabrication system.This paper reviews the phase mask and phase mask techniques,and its application to inscribe the fiberBragg gratings.It is noteworthy that the wavelength of the fiber Bragg grating would be tuned via onlya phase mask in a phase mask interferometer.In these systems,the fiber Bragg grating is inscribed byultra violet(UV)interference stripes derived from the optical components,where the phase mask is usedas a beam splitter of±1 order diffraction light.
