- Abstract
The high‐quality factors (Q‐factors) of nanocavities in three‐dimensional photonic crystals were experimentally demonstrated by increasing the in‐plane area of the structure. Entire structures made of GaAs were fabricated by a micro‐manipulation technique, and the nanocavities contained InAs self‐assembled quantum dots that emitted near‐infrared light. The obtained Q‐factor was improved to 93,000, which is 2.4 times larger than that in a previous report of a three‐dimensional photonic crystal nanocavity. Due to this large Q‐factor, a lasing oscillation from this cavity mode was successfully observed.
