## Abstract The simulation, fabrication and optical characterization of InGaN/GaN MQW‐LEDs grown by MOVPE over embedded photonic quasi‐crystals (PQCs) are reported. Fully coalesced GaN layers as thin as 140 nm were grown over 1200 nm high air‐gap PQCs using an intermittent pulsed/normal growth meth
