    • A multi-chip module (MCM) is described. This MCM includes two substrates having facing surfaces. Disposed on a surface of a first of these substrates, there is an optical waveguide, having an eigenmode in the plane of the surface, and an optical coupler, which redirects optical signals to and/or from the optical waveguide and a direction normal to the surface. Furthermore, disposed on a surface of a second of the substrates, which faces the surface of the first substrate, and which overlaps the optical coupler, there is an optoelectronic device. This optoelectronic device, which has an eigenmode in a direction perpendicular to the surface of the second substrate, selectively receives or provides the optical signal to and/or from the optical coupler. For example, the selective receiving or providing may be controlled by selectively applying a potential to the quantum-well device, thereby changing the optical properties of the optoelectronic device.
    • 描述了多芯片模块(MCM)。 该MCM包括具有相对表面的两个基板。 设置在这些基板中的第一个基板的表面上,存在在表面的平面中具有本征模的光波导和光耦合器,其将光信号重定向到和/或从光波导和垂直于 表面。 此外,设置在面对第一基板的表面并且与光耦合器重叠的第二基板的表面上,存在光电子器件。 该光电子器件在垂直于第二衬底的表面的方向上具有本征模式,选择性地接收或向光耦合器提供光信号。 例如,可以通过选择性地向量子阱器件施加电势来控制选择性接收或提供,从而改变光电器件的光学特性。
