Ultra-Dense Wavelength-Division Multiplexing With Microring Modulator

Journal of Lightwave Technology, 2021
Silicon photonics can be used to increase the versatility of wavelength division multiplexing (WDM). Ultra-dense wavelength division multiplexing (uDWDM) shrinks channel spacing between WDM channels to decrease guard bands and increase spectral efficiency.

Dense wavelength division multiplexing networks: principles and applications

IEEE Journal on Selected Areas in Communications, 1990
The very broad bandwidth of low-loss optical transmission in a single-mode fiber and the recent improvements in single-frequency tunable lasers have stimulated significant advances in dense wavelength division multiplexed optical networks. This technology, including wavelength-sensitive optical switching and routing elements and passive optical ...
