ABSTRACT:
An improved integrated optical device (5a-5g) is disclosed containing first and second devices (10a-10g; 15a, 15e), optically coupled to each other and formed in first and second different material systems. One of the first or second devices (10a-10g, 15a, 15e) has a Quantum Well Intermixed (QWI) region (20a, 20g) at or adjacent a coupling region between the first and second devices (10a-10g; 15a, 15e). 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 (SiO2), Silicon (Si), Lithium Niobate (LiNbO3), a polymer, or glass.
