The quality factor (Q), mode volume (V eff), and room-temperature lasing threshold of microdisk cavities with embedded quantum dots (QDs) are investigated. Finite element method simulations of standing wave modes within the microdisk reveal that V eff can be as small as 2(λ/n) 3 while maintaining radiation-limited Qs in excess of 10 5. Microdisks with a 2(More)
