Abstract
The use of a single-defect photonic band gap (PBG) cavity offers the possibility of spontaneous emission modification1 and nearly thresholdless laser operation.2 Recently, Caltech group demonstrated a single-defect PBG laser based on a dipole defect mode of two-dimensional (2D) triangular lattice.3 In this work, we propose and characterize a nondegenerate 2D monopole mode instead of the degenerate dipole mode as a candidate for a thresholdess PBG laser.
