Highly Effective Crosstalk Mitigation Method Using Counter‐Propagation in Semiconductor Optical Amplifier for Remodulation WDM‐PONs

open access: yesJournal of Photonics, Volume 2014, Issue 1, 2014., 2014
Remodulation‐induced crosstalk mitigation in WDM‐PON using remodulation approach is presented in this paper. Utilizing all‐optical signal processing, the proposed method has been able to significantly improve system performance in terms of bit error rate (BER) and bit rate distance product.

Reflective Semiconductor Optical Amplifier Chip with Low Ripple for C-Band External Cavity Narrow-Linewidth Laser

open access: yesPhotonics
The main characteristic of a reflective semiconductor optical amplifier chip (RSOA) is that it does not generate optical resonance under electric pumping and maintains the operation state of spontaneous emission.

Characterization of uncooled RSOA for upstream transmission in WDM reflective PONs

open access: yesOptics Express, 2012
We investigate on the uncooled RSOA driving parameters in WDM reflective PONs, focusing on an upstream path at 1.25 Gbit/s using pure binary modulation. We show how the optimal values change using direct-detection or self-coherent receivers. In particular, for the latter, the driving point optimization allows a gain of more than 3 dB in terms of ODN ...

Secondary Brown Carbon Formation From Photooxidation of Furans From Biomass Burning

open access: yesGeophysical Research Letters, Volume 51, Issue 1, 16 January 2024.
Abstract Furans are a major class of volatile organic compounds emitted from biomass burning. Their high reactivity with atmospheric oxidants leads to the formation of secondary organic aerosol (SOA), including secondary brown carbon (BrC) that can affect global climate via interactions with solar radiation.
