Quality Factor Control in Laterally-Coupled Vertical Cavities

Following the demonstration of quality factor (Q-factor) control in coupled photonic crystal nanocavities, we present our new research work on the Q-factor control in laterally coupled vertical cavities. Thermal-optic Q-tuning has been successfully observed when bringing a square-shaped vertical cavity and an adjacent Fabry-Pérot-like cavity into resonance. The approach paves the way towards a few quantum optical applications using vertical cavities.
