We first experimentally demonstrated a transverse magnetic (TM) mode laser ina Photonic crystal (PhC) slab structure at room temperature. This studyproposes a PhC nanobeam (NB) cavity to support a high-quality-factor (Q-factor)TM mode. For a large and complete photonic bandgap, the PhC NB structuresconsist of large air holes in a thick dielectric slab. The PhC NB cavity wasoptimized numerically for a high-Q-factor TM mode of over 1,000,000 by reducingthe radii of the air holes quadratically from the center to the edge of the PhCNB. A single TM mode lasing action was observed in an InGaAsP quantum-well(QW)-embedded optimized PhC NB cavity structure at room temperature via opticalpulse pumping, where the QW layer was lightly etched. We believe that the TMmode lasers in PhC NB cavities with a lightly etched QW can be good candidatesfor a surface plasmon excitation source or a highly sensitive optical sensor.
