Analyzing Transmission Spectra of Fiber-Optic Elements in the Near IR Range to Improve the Security of Quantum Key Distribution Systems

Transmission spectra of a fiber-optic isolator and a wavelength-division multiplexing (WDM) thin-film filter are measured in the 700–860 nm range of wavelengths. It is shown that the analyzed elements have optical transmission windows in the considered range that could negatively affect the security...

Description
Summary:Transmission spectra of a fiber-optic isolator and a wavelength-division multiplexing (WDM) thin-film filter are measured in the 700–860 nm range of wavelengths. It is shown that the analyzed elements have optical transmission windows in the considered range that could negatively affect the security of quantum key distribution systems.
