Abstract
Microcavity organic light emitting diode (OLED), otherwise a Fabry-Perot etalon, is essentially an optical resonator formed with the active electroluminescent organic emissive layer/s (EMLs) sandwiched between two partially reflecting mirrors. With a rigorous and efficient transfer matrix formalism technique, we present the numerical investigation of lattice defects introduced in a metal-dielectric photonic crystal (MDPC) by varying thickness of a layer of an organic molecule, Tris(8-hydroxyquinolinato) aluminum, AlQ3. We demonstrate the full normal emission of defect crystal, migrating behavior of the defect states, and anti-crossing features with formation of new hybrid states, mix of defected and normal crystal states. We also examine the electric field profile, and hence the perturbation in energy states to learn more about how defect states generate and resonate inside and out of the defected microcavity.
