Time-Division-Multiplexing–Wavelength-Division-Multiplexing-Based Architecture for ONoC

Journal of Optical Communications and Networking, 2017
Future many-core processors will require high-performance yet energy-efficient on-chip networks to provide a communication substrate for the continually increasing number of cores on one chip. Optical networkon- chip (ONoC) is employed as a promising candidate interconnection solution for its high bandwidth and low energy consumption.

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 ...

Mode-division multiplexed transmission of wavelength-division multiplexing signals over a 100-km single-span orbital angular momentum fiber

Photonics Research, 2020
We experimentally demonstrate mode-division multiplexed (MDM) transmission using eight orbital angular momentum (OAM) modes over a single span of 100-km low-attenuation and low-crosstalk ring-core fiber (RCF).

Wavelength-division multiplexing with femtosecond pulses

Optics Letters, 1995
We demonstrate wavelength-division multiplexing with a single broadband femtosecond source by slicing the 3.7-THz spectral bandwidth of 85-fs laser pulses into 16 channels that are modulated individually.
