| Summary: | The goal of this project is the experimental verification of the technique of Semi-Quasi-Phase Matching. For this purpose, samples of monocrystalline GaAs will be processed through deep etching and filled with polycrystalline GaAs powder. The experimental apparatus for measuring second harmonic generation is composed of a tunable CO2 laser, an InSb and an HgCdTe photodetectors both operating at low temperature. This project allows beginner student in undergraduate courses to become familiar with the techniques of microfabrication and instrumentation through the study of fundamentals and technology of lasers and non-linear optics. All manufacturing and assembly work were performed at the Device Research Laboratory (LPD), Department of Applied Physics, Institute of Physics Gleb Wataghin (IFGW). |
