Bilithic composite for optoelectronic integration.

摘要

Optoelectronic composite consisting of two chips, the first chip (10) being made of a first material, the second one (13) being made of another material. The first chip (10), for example, comprises a multiplicity of active optoelectronic devices e.g. a laser diode (11) and a photo diode (12), all being monolithically integrated. A multiplicity of other optical devices, e.g. a waveguide (16), is monolithically integrated on the second chip (13). In addition this second chip (13) has depressions of the size of the devices (11, 12) integrated on said first chip (10). These devices and the waveguide (16) of the second chip (13) are automatically aligned when flipping both chips together. <IMAGE>
