InGaAsN-GaAsSb type-II ‘‘W’’ quantum well structures have been grown by metalorganic chemical vapor deposition (MOCVD). Photoluminescence and X-ray diffraction measurements indicate that thin layers (2–2.5 nm) of GaAs1 ySby and InGaAs1 xNx can be grown with compositions of y 1⁄4 0:3 and x 1⁄4 0:02. ‘‘W’’ structures with different N contents indicate that emission wavelengths in the 1.4–1.6 mm range can be achieved. The use of GaAs0.85P0.15 tensile strained barrier layers is found to… Expand
