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

Journal 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.

UDWDM-PON using low-cost coherent transceivers with limited tunability and heuristic DWA [PDF]

, 2016
A new Passive Optical Network (PON) for access, making use of Ultra Dense Wavelength Division Multiplexing (UDWDM) by densely spacing channels at few GHz, and introducing the “wavelength-to-the-user” concept, is proposed.

Compatibility between coherent reflective burst-mode PON and TWDM-PON physical layers [PDF]

, 2014
We discuss the compatibility between reflective PON architectures and the recently defined ITU-T G.989.1 TWDM-PON. Focusing on the upstream, we experimentally demonstrate that, by using burst-mode coherent detection at OLT, reflective PON can achieve the

Micro‐Transfer Printed Continuous‐Wave and Mode‐Locked Laser Integration at 800 nm on a Silicon Nitride Platform

Laser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.
A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...
