Chao Gu, Yuhao Cheng, Xiaotian Zhu, Xiaolong Hu · 2015
A fractal design of superconducting nanowires integrated with nano-antennae is proposed to achieve polarization-insensitive single-photon detection. The simulated absorptance at 1550 nm for TE and TM polarizations are 80.1% and 80.3%, respectively.
