In this paper, we review our recent results from studies of growth and optical properties of GaAsN bulk epilayers and (In)GaAsN structures by using double crystal X-ray diffraction (DCXRD), photoluminescence (PL) and cross-sectional transmission electron microscopy (XTEM). We discuss the optimal growth conditions for obtaining high crystal quality GaAsN epilayers and (In)GaAsN/GaAs quantum well (QW) structures with high nitrogen composition. A newly designed GaAsN (QW) structure with multiple-InAs monolayers and 1.3 μm InGaAsN quantum well structure are also presented.
