A tensile-strained GeSn/SiGeSn multiple quantum well (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/SiGeSn lasers are attributed to the modulatio... https://megavitamines.shop/product-category/7-mushroom-super-blend/
