Title: The Innovative Contributions of Sébastien Bigo
Introduction
Sébastien Bigo is a prominent inventor based in Palaiseau, France. He has made significant contributions to the field of optical communications, holding a total of 9 patents. His work focuses on enhancing the efficiency and effectiveness of wavelength division multiplexing systems.
Latest Patents
Among his latest patents are two notable inventions. The first is a frequency allocation scheme and transmission system for polarization and wavelength division multiplexed signals with left and right side filtering. This invention presents a frequency allocation scheme for optical channels transmitted via a WDM transmission line, utilizing alternating left side and right side filtering for adjacent channels. The channels are orthogonally polarized, with alternating channel spacing of A and B, where A is less than B.
The second patent is a wavelength division multiplex transmission system using asymmetrical filtering. This invention addresses the spectral intervals between adjacent channels, which differ on either side of a channel. A demultiplexing filter is employed to attenuate the spectrum of the channel more strongly on the side with the smaller spectral interval. This innovation improves spectral efficiency while retaining frequencies chosen from a grid of regularly spaced frequencies.
