High-efficiency broadband fiber-to-chip coupler using a 3D nanoprinting microfiber
Dong-Hui Fan, Xing-Yu Zhang, Wei-Jun Zhang +6
We propose a method for coupling a tapered optical fiber to an inverted tapered SiN waveguide by fabricating a microfiber using 3D nanoprinting lithography. The microfiber consists…

Dark counts of superconducting nanowire single-photon detector under illumination
Sijing Chen, Lixing You, Weijun Zhang +5
An abnormal increase in the SDE was observed for superconducting nanowire single-photon detectors (SNSPDs) when the bias current (Ib) was close to the switching current (Isw). By i…
