Abstract

The concept of photonic crystal surface-emitting lasers (PCSELs) is introduced by etching a hexagonal pattern of small air holes into the top Bragg reflector of a conventional 980 nm-wavelength VCSEL structure. For certain current ranges, the resulting devices oscillate only on the fundamental transverse mode even for oxide aperture diameters up to 12 μm, yielding device resistances in the 50 Ω-regime.
