High efficiency operation of butt joint line-defect-waveguide microlaser in two-dimensional photonic crystal slab

Wanhua Zheng, Gang Ren, Mingxin Xing, Wei Chen, Anjin Liu et al.
Butt joint line-defect-waveguide microlasers are demonstrated on photonic crystal slabs with airholes in a triangular lattice. Such microlaser is designed to increase the output power from the waveguide edge directly. The output power is remarkably enhanced to 214 times higher by introducing chirped … [Appl. Phys.
