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.

Agile and Upgradeable Multi-wavelength Source for Dense Wavelength Division Multiplexing Networks

LEOS 2007 - IEEE Lasers and Electro-Optics Society Annual Meeting Conference Proceedings, 2007
We demonstrate a multi-wavelength source covering the whole C-band with 100 GHz or 50 GHz spacing on the ITU-T grid. Error-free operation of the modulated channels is obtained with identical performance to commercial DFB lasers.

Integration of both dense wavelength-division multiplexing and coarse wavelength-division multiplexing demultiplexer on one photonic crystal chip

Optical Engineering, 2013
An integrated model of photonic crystal (PC) demultiplexer that can be used to combine dense wavelength-division multiplexing (DWDM) and coarse wavelength-division multiplexing (CWDM) systems is first proposed. By applying the PC demultiplexer, dense channel spacing 0.8 nm and coarse channel spacing 20 nm are obtained at the same time. The transmission

Quantum key distribution for 10 Gb/s dense wavelength division multiplexing networks

Applied Physics Letters, 2014
We demonstrate quantum key distribution (QKD) with bidirectional 10 Gb/s classical data channels in a single fiber using dense wavelength division multiplexing. Record secure key rates of 2.38 Mbps and fiber distances up to 70km are achieved.
