Integrated Photonics Using Nanoimprint Lithography for Biophotonic Applications
Leuven | More than two weeks ago
Advancing the frontiers of highly efficient integrated photonic components using low-cost lithography.
Nanoimprint Lithography (NIL) is emerging as a cost-efficient fabrication approach capable of nanometer-to-micrometer-scale patterning with high fidelity and throughput. In NIL, a master template is fabricated using high-resolution lithography methods. This pattern is then imprinted into a UV sensitive resin on the device wafer. Nanophotonic components can be realized using the resin as functional waveguide material, or by etching the pattern into the underlying dielectric layer.

In the scope of this thesis, the student will design and characterize photonic integrated components operating in the visible range. The study will start with exploration of material stacks (polymers, resins, SiN etc) that are suitable for visible integrated photonics. Considering the properties of chosen materials, integrated photonic components such as grating couplers, waveguides, splitters, resonators etc will be designed. During the design process, the student will deepen his/her photonic integrated circuit design knowledge and master the widely used integrated photonics design packages. The designed optical components will be fabricated by different process teams at imec. As a final step, the fabricated structures will be characterized using optical setups. The work will also include some Matlab and Python scripting.
