| Abstract: | An improved method using white light interferometry and optical fiber Michelson interferometer to measure group refractive index is introduced. The measurement process is simplified when sandwiched sample is used and contacted with detecting fiber surface. The collimating between sample and the detecting fiber can be adjusted according to the change of the bandwidth of the reflective peak. |
