Deep neural network-based joint monitoring of carrier-to-signal power ratio (CSPR) and optical signal-to-noise ratio (OSNR) for directly detected optical single-sideband transmission

Optics Express
Optical single-sideband (SSB) transmission enhances spectral efficiency and mitigates transmission reach limitations caused by chromatic dispersion (CD), making it ideal for cost-effective data-center interconnects. This paper proposes and demonstrates deep neural network (DNN)-enabled optical performance monitoring (OPM) for optical SSB transmissions.

Wavelength conversion for WDM communication systems using four-wavemixing in semiconductor optical amplifiers [PDF]

, 1997
Four-wave mixing (FWM) in semiconductor optical amplifiers is an attractive mechanism for wavelength conversion in wavelength-division multiplexed (WDM) systems since it provides modulation format and bit rate transparency over wide tuning ranges.

Efficient binary phase quantizer based on phase sensitive four wave mixing [PDF]

, 2014
We experimentally demonstrate an efficient binary phase quantizer operating at low pump powers. Phase-sensitive operation is obtained by polarization mixing the phase-locked signal/idler pair in a degenerate dual-pump vector parametric ...
