The bias current dependences of the detection efficiencies at the 1550 nm wavelength and the dark count rates were systematically evaluated in the wide range of the strip widths. Single-photon ...

Numerical simulation results demonstrate that our designed HFMF can support 12 spatial modes with the min effective index difference between adjacent non-degenerated LP modes (Δneff) larger than ...
