Building Artificial Crystals with Organic LED Microcavities
Conference Year
January 2022
Abstract
Recent work has demonstrated the ability to produce electroluminescent photonic crystals by forming a vertical stack of OLED microcavities. The geometry of the crystalline unit cells sensitively determines the photonic energy states through hybridization of the microcavity resonance. We show that employing identical mirrors results in the formation of a single photonic emission band. We then break the symmetry of the crystal by introducing alternating mirrors, resulting in the creation of a mid-band photonic band gap. The thickness of the metallic mirrors is tuned to control the density of states and the photonic band gap.
