Photonic crystal devices have big potential for nonlinear optics, as they can confine light both spatially and temporally. However, a large number of nonlinear optical processes can occur in these systems, making it…
The ability to measure very precise alignments and displacements is a key requirement for many steps in semiconductor fabrication and manufacturing, for example, during lithography or wafer bonding. Using small…
One of the key tasks in integrated photonics is the separation or demultiplexing of multiple different wavelength channels that are transported through the same waveguide. One way to separate different wavelength is to…
One problem in silicon photonics is that current integrated light sources are very sensitive to variations in the operating temperature. Together with the Centre for Advanced Photonics & Process Analysis we have…
In collaboration with the Centre for Advanced Photonics and Process Analysis at the Cork Institute of Technology, we have demonstrated a low loss optical buffer based on photonic crystal cavities, demonstrating a…
