    "abstract": "We proposed and realized a two-dimensional (2D) photonic bandedge laser\nsurrounded by the photonic bandgap. The heterogeneous photonic crystal\nstructure consists of two triangular lattices of the same lattice constant with\ndifferent air hole radii. The photonic crystal laser was realized by\nroom-temperature optical pumping of air-bridge slabs of InGaAsP quantum wells\nemitting at 1.55 micrometer. The lasing mode was identified from its spectral\npositions and polarization directions. A low threshold incident pump power of\n0.24mW was achieved. The measured characteristics of the photonic crystal\nlasers closely agree with the results of real space and Fourier space\ncalculations based on the finite-difference time-domain method.",
