Abstract :
InGaAsN lasers with asymmetrically placed active region were fabricated and characterized. By moving the QW closer to p-cladding layer, reduced hole transport time in separate confinement heterostructure (SCH) results in lower threshold current, higher injection efficiency and its characteristic temperature. The experimental results agrees well with calculation.
