Theoretical Investigation of Tensile-Strained GeSn/SiGeSn Multiple Quantum Well Laser Wrapped in Si 3N4 Liner Stressor
A tensile-strained GeSn/SiGeSn multiple quantum well ball stop (MQW) laser wrapped in Si3N4 liner stressor is designed and characterized theoretically.A biaxial tensile strain is introduced into the GeSn/SiGeSn MQW laser by the Si3N4 liner stressor.The boosting effects of tensile strain on the threshold current density Jth and optical gain in GeSn/
