Abstract
Wide stripe and single-mode ridge guide dilute nitride quantum well lasers exhibit high performance in the 1.3 micron wavelength region. Optimizing the MOCVD growth of InGaAsN has yielded devices displaying reduced temperature sensitivity compared with conventional InP-based structures. Current annealing effects in InGaAsN QW lasers are minimized through the use of a nitrogen only cool down after growth of the laser structure. Device studies reveal the impact of nitrogen content and quantum well barrier materials on the optical gain, carrier confinement, and laser characteristics. Extension of the emission wavelength in MOCVD grown structures remains challenging. Higher N content results in a significant increase in threshold current density and higher temperature sensitivity.
