In this thesis, we study all-optical processing techniques based on non-linear semiconductor optical amplifiers for the functionalities of second and third generation optical networks. In particular, devices for all-optical wavelength conversion with regenerative properties have been investigated. The configurations under investigation are based on the non-linear four-wave mixing process which ...
This chapter is dedicated to the presentation of basic concepts plasma diagnostics via spectroscopy techniques, including optical emission and absorption spectroscopy. The measurements temperature electron density are illustrated several examples transient atmospheric plasmas generated by electrical discharges, for which validity conditions limitations discussed. Finally, influence self-absorpt...
Ellipsometric determination of optical constants for silicon and thermally grown silicon dioxide via a multi-sample, multi-wavelength, multi-angle investigation" (1998). Optical constant spectra for silicon and thermally grown silicon dioxide have been simultaneously determined using variable angle of incidence spectroscopic ellipsometry from 0.75 to 6.5 eV. Spectroscopic ellipsometric data set...
