中文摘要	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 structure in the output waveguide. the lasing mode operates in the linear dispersion region of the output waveguide so that the absorption loss due to the band-edge effect is reduced. the laser resonance is illustrated theoretically using the finite difference time domain method. a practical high power efficiency of 20% is obtained in this microlaser.
