Claim 0:
1. An assembly of an active semiconductor component and of a silicon-based passive optical component, said assembly comprising:
a carrier; and
said active semiconductor component and said passive optical component both arranged on said carrier, and wherein:
said active semiconductor component comprises:
a first set of semiconductor layers comprising at least one first waveguide configured to guide, in a first section of the assembly, at least one first optical mode;
a second set of semiconductor layers, said set being superposed and making contact with said first set of layers, and comprising at least one second waveguide configured to guide at least one second optical mode; wherein
at least some of said layers of the first set of layers and of the second set of layers are doped to form, in a first region of the component, a PIN diode;
said at least one first waveguide and said at least one second waveguide are configured to allow evanescent coupling therebetween, in a second section of the assembly;
said first set of layers is etched to form, in a second region of the active semiconductor component, a first surface flush with said second waveguide;
said passive component comprises:
a substrate;
a set of silicon-compound layers comprising at least one waveguide configured to guide at least one optical mode; and wherein:
said at least one waveguide lies flush with a first surface of said set of layers, which surface is opposite a second surface of said set of layers making contact with a surface of the substrate; and wherein
said first surface of the passive optical component makes contact with said first surface of said active semiconductor component in order to allow evanescent coupling between said at least one waveguide of the passive optical component and said at least one second waveguide of said active semiconductor component.
