Abstract
We propose modulated PCSELs (M-PCSELs) with a double lattice and a Q-switching mechanism for emitting structured light. A 28-dot pattern with a peak power of >5W is successfully generated at a current injection of ~1A, where the pulse width is <100ps and each dot has a narrow divergence angle of <0.5°.
