Feasibility study of SOA-based noise suppression for spectral amplitude coded OCDMA [PDF]
, 2007 We investigate the benefits of employing a saturated SOA to reduce optical noise in an incoherent light OCDMA system. In the context of spectrum-slicing, SOA-based noise suppression has shown significant potential for enhancing the signal quality of ...

Suppression of Cavity Time-Delay Signature Using Noise-Phase-Modulated Feedback
IEEE Access, 2020 We propose reconfiguration of the conventional feedback scheme to suppress the external-cavity time-delay signature (TDS) by adding noise phase modulation in the feedback of semiconductor laser.

Noise suppression of incoherent light using a gain-saturated SOA: implications for spectrum-sliced WDM systems [PDF]
, 2005 In this paper, we present an experimental and numerical study of semiconductor optical amplifier (SOA)-based noise suppression and its relevance to high-channel-density spectrum sliced wavelength-division-multiplexed systems. We show that the improvement

Effects of weak input side mode suppression ratio and output filtration on the intensity noise of a self-seeded gain switched optical pulses at 2.5 GHz [PDF]
, 2005 Mode partition noise is shown to be a cause for concern in terms of the intensity noise induced on a self-seeded gain-switched pulse when filtering is used to increase the side mode suppression ratio (SMSR) of the output signal to >30 dB.

Corn plants as temporary acoustic barrier to limit the effects of noise pollution
, 2021 Corn is a cereal imported into Europe from the Americas. It is used for human and animal feed, but there are also industrial uses such as the production of ethanol, of fuel for heating homes, or the production of starch. Corn grows in the summer in areas
