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

PhC based tunable optical buffer

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 record low loss per storage time. The delay … Continue reading
