Ultrahigh-efficiency wavelength conversion in nanophotonic periodically poled lithium niobate waveguides [PDF]
Optica, 2018 Periodically poled lithium niobate (PPLN) waveguide is a powerful platform for efficient wavelength conversion. Conventional PPLN converters however typically require long device lengths and high pump powers due to the limited nonlinear interaction ...

On Wavelength-Routed Networks With Reversible Wavelength Channels [PDF]
Journal of Lightwave Technology, 2013 We observe that the performance of wavelength- routed (WR) networks often suffers from asymmetric traffic and network traffic patterns differing from the original design plans. WR networks with a fixed number of channels in a given transmission direction are inflexible. Therefore, we propose reversible wavelength channels.

On the biphoton wavelength [PDF]
Brazilian Journal of Physics, 2001 We report on an experiment showing that the wavelength of a biphoton is clearly dependent on the measurement scheme and on the way it is defined. It is shown that it can take any value, depending on the control of the interferometer phase differences.
