Introduction

Yann Loussouarn is a notable inventor based in Lannion, France. He has made significant contributions to the field of optical transmission technology, holding three patents that showcase his innovative approach to solving complex problems in this domain.

Latest Patents

One of his latest patents is a method and device for controlling the load of an optical transmission line with wavelength-division multiplexing. This invention involves a load-controlling device that manages the load on an optical transmission line, which is coupled to an emitting device. The device modulates data and multiplexes multiple useful wavelengths into a single optical signal for transmission. It includes elements that generate a filler optical signal composed of at least one wavelength that is not modulated by data, which is injected into the optical transmission line. The control module of this device selects the wavelength of the filler optical signal based on information indicating the non-turn-on of a wavelength among the useful optical signals.

Another significant patent by Loussouarn is related to the determination of an optical signal to noise ratio of a dual-polarization optical signal. This method involves detecting a modulation signal within the dual-polarization optical signal and determining the optical signal to noise ratio from the measurement of the power of this modulation signal.
