Abstract:
A quantum key distribution system is deployed in an optical fiber network transporting classical data traffic. A source of entangled photon pairs is used to generate quantum keys. Classical data traffic is typically transported over channels in the C-band. If a pair of channels for transport of quantum data is available within the C-band, then the source of entangled photon pairs is tuned to emit in a pair of channels in the C-band. If a pair of channels for transport of quantum data is not available within the C-band, then the source of entangled photon pairs is tuned to emit in a pair of channels in a combined S-band and L-band. When a periodically-poled lithium niobate waveguide pumped with a laser is used for the source of entangled photon pairs, the output spectral properties are tuned by varying the temperature of the waveguide.

Claim (Index 19):
The computer readable medium of  claim 15 , wherein the transmitting quantum data via a selected frequency band comprises:\n transmitting from the first optical source a pair of entangled photons in a second pair of channels in a second frequency band in response to determining that the first pair of channels for data transport is not available in the first frequency band.
