Future optical modulators have to satisfy requirements that current electro-optical modulators fail to do, such as very low command voltage, small size and ability to work in the 0-40GHz range with low losses. It is also necessary to find new ways to modulate light at a faster speed but with low consumption. The work in this thesis addresses these above mentioned problems within the framework of an upstream project which has been financed by the French Ministry of Defence. Its goal is to evaluate the potential gain of plasmonics in the field of semiconductors based optical modulation. We first select a gallium nitride based structure on sapphire whose optical properties exhibit very low propagation losses of 0.6dB/cm. Then we proved the gen...
