High Dynamic Range Externally Time-gated Photon Counting Optical Time-domain Reflectometry
Bin Li, Guangwei Deng, Ruiming Zhang +8
Single photon detector (SPD) has a maximum count rate due to its dead time, which results in that the dynamic range of photon counting optical time-domain reflectometry (PC-OTDR) d…

The effect of gravitational spin-orbit coupling on the circular photon orbit in the Schwarzschild geometry
Zhi-Yong Wang, Cai-Dong Xiong, Qi Qiu +2
The (1, 0)+(0, 1) representation of the group SL(2, C) provides a six-component spinor equivalent to the electromagnetic field tensor. By means of the (1, 0)+(0, 1) description, on…
