SMF-Coupled Compact Ground Terminal with Advanced Filtering Towards Daylight C-Band Satellite QKD

Year: 2025

Type: conference-paper

Abstract: We demonstrate a compact, high-isolation C-band optical ground terminal for satellite-QKD, achieving more than 120 dB daylight background suppression and 135 dB crosstalk noise isolation. Successful QKD over an outdoor 100 m FSO validate its feasibility for integration of satellite QKD with urban fiber segments. ©2025 The Author(s)
