Fabrication and performance of GaN-based two dimensional photonic crystal surface emitting lasers

We demonstrated GaN-based two-dimensional photonic crystal surface emitting lasers with a low threshold pumping energy density of about 2.7 mJ/cm 2 and a large spontaneous coupling factor of 5times10 -3 , and lasing actions from three different band-edges.
