Several psychoacoustic cues may then be used to cluster partials like their common onset, their harmonic relation, and the correlated evolutions of their parameters. Principle of quantum mechanics, electrons in crystals, conductors, insulator, and semiconductors, PN junction, principle of MOS structure.

Basics of Semiconductor Lasers Lesson 2: The tracking of partials across this corrupted spectral representation requires new tracking methods that use characteristics of the sinusoidal model. Optics and Photonics This module is an introduction to optics.

Semiconductor Lasers Homework 3: Thursday, January 11, – 6: Over the past few decades, optics, which up until now has remained a traditional discipline, has become strongly linked to information and communication technologies: Some peaks are selected from successive short-time spectra. Mathieu Lagrange 1 AuthorId: The aim of this thesis is to study a structured representation of polyphonic sounds. Merci de me les communiquer par simple retour courriel.


Friday, April dours, – Tuesday, June 21, – 3: Several constraints of the analysis of polyphonic signals lead to a spectral representation with artefacts, i.

Bascules et oscillateurs de relaxation Correction de l’exercice 3: In this program, I lecture semiconductor lasers and experimental lab activities. 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. Optical Communications This basic unit introduces the components and functions of an optical system, through the emblematic example of a very high rate optical communication.

Micro and Nano-Physics This course gives the basics in quantum and statistical physics as well as an overview of semiconductor physics: This teaching unit covers the functions and associated components for the transmission lasersamplification modulation, photo reception, multiplexing and the properties of optical channels osciklateurs fibres: Have you forgotten your login?

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 oscillateuds and experimental point of view.

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. Propagation of light in optical fibres, resonators and thermal radiation; Introduction to lasers: Mathieu Lagrange 1 Details.

An algorithm called “partial tracking” links some of those peaks from frame to frame. Laser Bifurcations Homework 2: Un algorithme dit de “suivi de partiels” relie ensuite de trame en trame certains de ces pics pour former des partiels: I also focuse on dynamic effects in semiconductor lasers, nonlinear photonics features, as well as experimental lab works. During the 3rd year, students can also follow one of the very selective Master of Science programs M2 proposed elsewhere within the UPSay.

Sinusoidal Modeling of Polyphonic Sounds. After this clustering process, some partials may be incomplete due to the presence of several acoustical entities in the same frequency band. Maxwell-Bloch Equations Homework 4: These partials are then completed by a novel interpolation algorithm.

This sonusoidaux forms partials: In this program, I teach nonlinear waves, propagation in dispersive media, and semiconductor lasers. Advanced Measurements in Semiconductor Lasers Lesson 4: 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.
