Etude et réalisation d'un spectromètre compact en optique intégrée sur verre

Abstract : Optical spectrum analysis enables the study of materials chemical composition through matter and radiation interaction. In recent years, spectrometry in the near infrared has been developed to meet needs in areas such as medicine, gas detection and polymer industry. In this thesis, a new concept of static Fourier transform spectrometer using a leaky bent optical waveguide structure is investigated. An electromagnetic model of this structure has been developed in order to design the spectrometer. This model is based on a modal Fourier decomposition applied in the conformal mapping and is implemented using absorbing layers. First spectrometers have been realized using glass integrated optics and have been characterized. Spectral resolutions of 11 nm and 14 nm have been measured. These results are encouraging to carry on further the development of this spectrometer.
