An improved integrated optical device ( 5 a- 5 g) is disclosed containing first and second devices ( 10 a- 10 g ; 15 a , 15 e), optically coupled to each other and formed in first and second different material systems. One of the first or second devices ( 10 a- 10 g , 15 a , 15 e) has a Quantum Well Intermixed (QWI) region ( 20 a , 20 g) at or adjacent a coupling region between the first and second devices ( 10 a- 10 g ; 15 a , 15 e). The first material system may be a III-V semiconductor based on Gallium Arsenide (GaAs) or Indium Phosphide (InP), while the second material may be Silica (SiO<SUB>2</SUB>), Silicon (Si), Lithium Niobate (LiNbO<SUB>3</SUB>), a polymer, or glass. |
