• CEA-Grenoble (France) - R&D Engineer

  PARIS 2015 - maintenant CEA-Leti, a Grenoble, France-based research institute for electronics and information technologies, is one of the world’s largest organizations for applied research in microelectronics and nanotechnology. Today, the CEA-Leti is granted over 286 patents a year and handles a portfolio of more than 2,200 patented inventions.
  
  R&D Engineer
  Development of a Non-destructive Optical Diagnosis System.
  Development of new applications of terahertz radiation (TDS & CW).
  Responsibilities:
  • MATLAB/LabVIEW expert
  • Advanced Test bench & Software Developer
  • Purchasing management of new THz equipment (~200 k€): writing tender proposals, financial and technical evaluation of bidders.
  Achievements:
  • R&D on Non-destructive Optical Diagnosis in THz Frequency Domain
  • I designed and developed multiple optical test benches
  • I developed multiple applications using LabVIEW for Data Acquisition, Instrument Control, Automated Inspection and Test Measurement.
  • Advanced software architecture: Queued Message, State Machine, Producer/Consumer.
  • I developed an Advanced Data Analysis Software for Simultaneous Extraction of Dielectric Parameters and Thickness. The software uses sophisticated extraction algorithms (inverse problem solving) to deliver highly precise information of the complex material parameters of a sample (n, α, κ, ε', ε''), and the estimated sample thickness. My expertise in MATLAB includes object oriented design (OOP), development of high performance functions, graphical user interfaces, algorithm development, parallel computing and data analysis.
  
  • I have written many pieces of software for processing and converting raw data. I identified that a key piece of software we used for interacting with an instrument was coded in an unsupported language and took the initiative to code a MATLAB and LabVIEW TCP/IP Client application. This allowed us to use more complex online analysis and visualization in real-time during instrument testing.
  
  • On my initiative, to maintain continued collaboration with IMEP-LAHC Laboratory, I developed a new software to design and analyze diffractive structures to suit Disruptive THz Applications. I Built THzDiffAnalyzer software with the object-oriented programming of MATLAB. THzDiffAnalyzer provides a friendly user interface facilitating the calculations for reflection and transmission coefficients of 1D & 2D periodic structures (such as optical gratings, photonic crystals, etc.) based on the Fourier-Modal Method (FMM). To model an infinitely periodic grating, we only need to consider a single period of the grating. THzDiffAnalyzer allows to control the orientation of the illumination by rotating the plane wave both in-plane and out-of-plane, Sweep Frequency Response Analysis, etc.

• IMEP-LaHC - Research Scientist

  2010 - 2014 IMEP-LAHC Laboratory – Grenoble/Chambéry France, 180 researchers
  Research activities of IMEP-LaHC cover large areas (technologies, micro and nano-electronics, photonics, optical and microwaves telecommunications, Terahertz) which allow carrying out multidisciplinary research in common with our partners in nanophysics, material chemistry, circuit designers or system manufacturers in electronics and optoelectronics.
  My role at IMEP-LAHC Laboratory covered a wide range of activities from electromagnetic simulation & modeling of light-matter interactions to instrument testing, data analysis and signal processing. The main focus has been to develop new THz application areas such as the identification and/or unitary authentication of commercial items, identity papers and access control. In a real identification test, a coding capacity of nearly 20-bit has been demonstrated.
  
  Responsibilities:
  • Exploitation of new THz application areas
