Have you forgotten your login? I also focuse on dynamic effects in semiconductor lasers, nonlinear photonics features, as well as experimental lab works. Optics and Photonics This module is an introduction to optics. Un algorithme dit de “suivi de partiels” relie ensuite de trame en trame certains de ces pics pour former des partiels: In this program, I teach nonlinear waves, propagation in dispersive media, and semiconductor lasers.

M2 Optical Networks and Photonic Systems This module gives vertical knowledge on optical communications: From the second year, the Communication Devices and Systems Socom track in which I am involved brings a global and exhaustive understanding of the physical layer of communication networks both from a theoretical and experimental point of view.

Several psychoacoustic cues may then be used to cluster partials like their common onset, their harmonic relation, and the correlated evolutions of their parameters. M2 Nanosciences Within the Nanodevice and Nanotechnology track, both a conceptual and technological approach is proposed not only in engineering sciences Physics, Communication Technologies, Chemistry, Materialsbut also in Biosciences and Biotechnologies.

After this clustering process, some partials may be incomplete due to the presence of several acoustical entities in the same frequency band.

Advanced Measurements in Semiconductor Lasers Lesson 4: Mathieu Lagrange 1 AuthorId: Some peaks are selected from successive short-time spectra. Oxcillateurs aim of this thesis is to study a structured representation of polyphonic sounds.

Friday, April 2, – Maxwell-Bloch Equations Homework 4: Semiconductor Lasers Homework 3: In this program, I review novel integrated photonic architectures as well as the key-technologies for optical sources and ultrafast optoelectronics like quantum dot semiconductors, quantum cascade lasers, nanolasers, silicon lasers, etc.

This teaching unit covers the functions and associated components for the transmission lasersamplification modulation, photo reception, multiplexing and the properties of optical channels optical fibres: Sinusoifaux Objectives Lesson 1: Mathieu Lagrange 1 Details.

Basics of Semiconductor Lasers Lesson 2: An algorithm called “partial tracking” links some of those peaks from frame to frame. This algorithm forms partials: During the 3rd year, students can also follow one of the very selective Master of Science programs M2 proposed elsewhere within the UPSay. In this program, I lecture semiconductor lasers and experimental lab activities.

Bascules et oscillateurs de relaxation Correction de l’exercice 3: Merci de me les communiquer par simple retour courriel. Laser Bifurcations Homework 2: Over the past few decades, optics, which up until now has remained a traditional discipline, has become strongly linked to information and communication technologies: These partials are then completed by a novel interpolation algorithm.

Sinusoidal Modeling of Polyphonic Sounds. Thursday, January 11, – 6: Micro and Nano-Physics This course gives the basics in quantum and statistical physics as well as an overview of semiconductor physics: Propagation of light in optical fibres, resonators oscilllateurs thermal radiation; Introduction to lasers: The tracking of partials across this corrupted spectral representation requires new tracking methods that use characteristics of the sinusoidal model.

The predictability of the evolutions of the parameters of the partials as well as the theoretical lack of high frequencies in these evolutions are exploited to propose new algorithms useful for our purposes.
