摘要: A method of measuring the complex modulation a Bragg grating is derived from one-dimensional model light propagating in an optical fiber. Interference fringes between and reference air-gap reflector are measured, Fourier transform interference generated as laser swept through wavelength used to compute function over restricted domain. Supporting data, taken by temperature tuning distributed feedback diode laser, shown.
