This temperature dependence can be entirely attributed to the change in the Verdet constant of the glass. This is, to our knowledge, the first report of a birefringence free fiber-optic current sensor with Verdet constant limited performance. The sensor's response to current is linear to within...
1) Verdet constant 费尔德常数1. We derive the relationship between Verdet constant of magneto-optic glass and operating wavelength by the dispersion theory of Verdet constant. 对ZF1、ZF6磁光玻璃费尔德常数的色散特性进行了理论分析,得出磁光玻璃费尔德常数与工作波长的关系,并进行了实验验证,实验结果和...
2017, Journal of Non-Crystalline Solids Citation Excerpt : While in case of this study, the improvement of Verdet constant with 0.1% Tb doping can be attributed to the high polarization, high optical basicity and low melting temperature of host glass, which in turn accelerate the Tb4 + format...
