Configuration of time-division interferometer for stability enhancement of one-way QKD system
Jeong-sik Cho, Sae-kyoung Kang, Kwangjoon Kim · 2010
We propose a configuration method of a time-division interferometer for stability enhancement of a phase-encoded one-way quantum key distribution system. An optical phase modulator was placed outside of an optical interferometer to shorten the optical path length of the optical fiber-based interferometer.
