1310-nm quantum key distribution system with up-conversion pump wavelength at 1550 nm.
We show that the performance of a 1310-nm quantum key distribution (QKD) system with up-conversion detectors pumped at 1550 nm is comparable with or better than that of current 1550-nm QKD systems with a pump at shorter wavelength. The nonlinearly-induced dark counts are reduced when the wavelength of the pump light is longer than that of the quantum signal. We have developed a 1550-nm pump up-...
متن کاملPerformance Assessment of 1310 to 1550 nm Wavelength Conversion
We report on all-optical 1310 to 1550 nm wavelength conversion and NRZ-to-RZ data format conversion based on nonlinear polarization rotation in a single semiconductor optical amplifier. Introduction Undoubtedly, the 1310 nm transmission window is experiencing renewed interest. Multi-Gbit/s 1310 nm transmission technology is employed in access and metro networks [1-2]. The long-haul core network...
متن کاملFiber-optic quantum key distribution at 1550 nm
Quantum key distribution (QKD) invented by Bennett and Brassard in 1984 is a technique for sharing an assuredly secret, cryptographic key over unsecured optical links [1]. In QKD, information is encoded in the quantum state of individual photons and security is guaranteed by photons' fundamental quantum properties. Since the first demonstration of QKD over 40 cm in 1992, QKD has been extensivel...
متن کاملQuantum key distribution at 1550 nm using a pulse heralded single photon source.
Quantum key distribution with pulsed heralded single photon source was performed over 40 km of fiber for the first time to our knowledge. QBER was measured to be 4.23% suggesting security against unconditional attack.
متن کاملAll-optical 1310 to 1550 nm wavelength conversion by utilising nonlinear polarisation rotation in semiconductor optical amplifier - Electronics Letters
Introduction: One of the key components in all-optical communication networks using the whole low-loss bandwidth of the silica fibre is an ultra-wideband wavelength converter [1]. Use of all-optical ultrawideband wavelength converters enhances network flexibility, allowing an all-optical wavelength conversion between different transmission windows, and therefore avoiding the bottleneck of optic...
