Abstract
Very low threshold 1.5 mu m-wavelength GaInAsP/InP distributed feedback las ers consisting of deeply etched double quantum-well wire-like active region s have been successfully realised by CH4/H-2 reactive ion etching and metal organic vapour phase epitaxial regrowth. A threshold current density J(th) of as low as 94A/cm(2) was achieved for an active region width of 115nm an d cavity length of 600 mu m.
