Abstract: Methods for modifying multi-mode optical fiber manufacturing processes are disclosed. In one embodiment, a method for modifying a process for manufacturing multi-mode optical fiber includes measuring at least one characteristic of a multi-mode optical fiber. The at least one characteristic is a modal bandwidth or a differential mode delay at one or more wavelengths. The method further includes determining a measured peak wavelength of the multi-mode optical fiber based on the measured characteristic, determining a difference between the target peak wavelength and the measured peak wavelength, and modifying the process for manufacturing multi-mode optical fiber based on the difference between the target peak wavelength and the measured peak wavelength.

Abstract: A quantum communications system includes a quantum key generation system having a photonic quantum bit generator, a low loss dispersion limiting fiber having a length L, for example greater than 200 km, and a photon detector unit and a communications network having a signal generator, a signal channel, and a signal receiver. The low loss dispersion limiting fiber extends between and optically couples the photonic quantum bit generator and the photon detector unit. Further, the low loss dispersion limiting fiber is structurally configured to limit dispersion at an absolute dispersion rate of about 9 ps/(nm)km or less, and preferably 0.5 ps/(nm)km or less, and induce attenuation at an attenuation rate of about 0.175 dB/km or less such that the quantum key bit information of a plurality of photons output by the one or more photonic quantum bit generators is receivable at the photon detector unit at a bit rate of at least 10 Gbit/sec.

Abstract: A method of communicating information includes generating a photon pulse using an entangled photon generator. The photon pulse includes a photon pulse state and is temporally positioned within a photon pulse time slot. When the photon pulse is in a populated photon pulse state, it includes first and second entangled photons and the entangled photon generator outputs the first entangled photon into a first photon pathway optically coupled to an output end photon detector unit, and the second entangled photon into a second photon pathway, optically coupled to a receiving end photon detector unit. The method also includes determining the photon pulse state of the photon pulse using the output end photon detector unit, which outputs a signal regarding the photon pulse state of the photon pulse into a signal pathway to provide the receiving end photon detector unit with information regarding the photon pulse state of the photon pulse.
