Paper Abstract

Femtosecond laser is used to inscribe the reflectivity-changed mirrors in the single mode fiber that formed the device named cascaded Fabry-Perot micro-cavities, with details of fabrication given. The cascaded Fabry-Perot micro-cavities are made up of three reflected mirrors with different lengths of microcavities. By establishing the theoretical model of the device with the transfer matrix method, the effect of the cascaded Fabry-Perot micro-cavities can be seen as a superposition of the two Fabry-Perot cavities. Its reflection fringe contrast is experimentally up to 10dB. The proposed structure is regarded as an effective way to strengthen the contrast in order to improve the sensing resolution.
