Abstract
Photonic crystal surface emitting lasers emitting up to 2.6 µm have been designed and fabricated. A high-index-contrast photonic crystal layer was incorporated into the laser heterostructure by air-hole-retaining epitaxial regrowth. Transmission electron microscopy studies demonstrated uniform and continuous regrowth of the nano-patterned GaSb surface with AlGaAsSb alloy until air-pockets start being formed. The photonic crystal surface emitting lasers based on diode laser and cascade diode laser heterostructures generated narrow spectrum low divergence beams with mW-level output power. The angle-resolved electroluminescence analysis demonstrated well resolved photonic subbands corresponding to Γ2 point of square lattice and photonic gaps of several meV.
