Temperature and strain sensitivity measurements of high-birefringent polarization-maintaining fibers.
نویسندگان
چکیده
The strain and temperature sensitivities of three common commercial high-birefringent polarizationmaintaining fibers (bow-tie, polarization-maintaining and absorption-reducing, and elliptical core fibers) have been measured by using a dynamic polarimetric method. The experimental setup and measuring process are described in detail. Where possible, the measuring data are compared with published data, and good agreement is obtained.

Uncertainty of the Sagnac interferometer-based measurement of the modal birefringence of polarization maintaining optical fibers
Presented is an analysis of the expanded uncertainty of an indirect measurement of modal birefringence of polarization maintaining fibers, based on the Sagnac interferometer and an optical spectrum analyzer. By using this method it is easy to achieve an expanded measurement uncertainty considerably lower than 1%, at a confidence level of 0.95, in measurements of fibers, whose birefringence is i...
متن کاملExperimental study of polarization properties of highly birefringent photonic crystal fibers.
We analyze experimentally the polarization properties of highly nonlinear small-core photonic crystal fibers (PCFs) with no intentional birefringence. The properties of recently emerged polarization maintaining PANDA PCFs are also investigated. The wavelength and temperature dependence of phase and group delay of these fibers are examined in the telecommunications wavelength range. Compared to ...

متن کاملPrecision measurement of modal birefringence of highly birefringent fibers by periodic lateral force.
Applications of single-mode fibers to coherent optical fiber communication systems1 and fiber sensor systems2 require a definite state of polarization along the fiber length. Polarization-maintaining fibers such as elliptically clad3 and stress-applied4 single-mode fibers have a high internal birefringence that exceeds perturbing birefringence and produces linear polarization along the fiber. O...
متن کاملNovel technique for distributed fibre sensing based on coherent Rayleigh scattering measurements of birefringence
A novel distributed fibre sensing technique is described and experimentally validated, based on birefringence measurements using coherent Rayleigh scattering. It natively provides distributed measurements of temperature and strain with more than an order of magnitude higher sensitivity than Brillouin sensing, and requiring access to a single fibre-end. Unlike the traditional Rayleigh-based cohe...
