Wavelength-Shift-Keying (WSK) by using wavelength discrimination circuit in WDM networks

摘要

A wavelength-shift-keying (WSK) proof-of-concept experiment was demonstrated by using tunable laser and wavelength discriminator with both 2-level and 3-level modulations. Basic applications of this new technology have been discussed. The WSK could potentially be a high-speed and flexible transmission technology for future optical networks.
