| description | A TM<sub>0</sub> mode coupled travelling wave SNSPD based on SOI platform is designed. The light propagating in this device can achieve high-efficiency mode conversion from TE<sub>0</sub> mode to TM<sub>0</sub> mode and then absorbed by NbN nanowires on top of the waveguide. Thanks to the TM<sub>0</sub> mode coupled detection, the length of NbN nanowire that is needed to achieve a close-to-unity photon absorption is cut down to an extremely short level of ∼5 μm. Meanwhile, this TM<sub>0</sub> mode coupled travelling wave SNSPD is very robust against fabrication errors compared with TE<sub>0</sub> coupled SNSPD. |
