Nanoscale displacement sensor

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 nanoparticles, exhibiting a Huygens dipole coupled to crossed Photonic crystal … Continue reading

Flat-band superprism in photonic crystals

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 use refraction in a prism and the … Continue reading

Thermally stable integrated laser

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 developed a hybrid laser with an external reflector … Continue reading
