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 can be tuned dynamically over a range of more than 150ps.
