Plasmonics - The path towards smallest optical devices
In this work we will investigate the realization of plasmonic resonant modulators. The resonance enables a massive reduction in size, however, this makes fabrication challenging. In this master project you will help to find a fabrication procedure to realize such structure.
Today’s photonic devices can process data way faster than electronic devices. However, their minimal footprint cannot be reduced to the sub-wavelength regime. This condition complicates the progress towards highly integrated ultra-fast electro-optic devices. Plasmonics can bridge this gap.

Plasmonics confines light to the sub-wavelength regime resulting in strong electromagnetic fields. This effect allows weak nonlinear processes, which depend quadratic or cubic on the local field strength, to be enhanced significantly.
