摘要:
Fiber Fabry-Perot etalon (FFPE) is a device designed as an optical frequency filter, and its transmission characteristics change depending on temperature. The temperature dependence of the transmission frequency of an FFPE made of a highly birefringent fiber was found to be -2:31 GHz/deg, which is almost the same as that of a conventional etalon. On the contrary, its temperature dependence of the transmission frequency separation due to birefringence was found to be -140 MHz/deg. This is about 18 times larger than that for a conventional FFPE, and it implies that an FFPE made of highly birefringent fiber is promising as a temperature sensor with a high precision.
