Optical Module Stacked Architecture for Heat Dissipation

The patent introduces a three-dimensional stacked architecture where optoelectronic devices are arranged in multiple layers vertically rather than only horizontally. This dimensional transition allows compact integration while maintaining thermal pathways to heat dissipation structures positioned at different vertical levels, effectively separating heat generation zones from heat dissipation zones.

The patent employs thermal interface materials and heat dissipation structures positioned between the closely distributed optoelectronic devices and the external environment. These intermediary elements facilitate efficient heat transfer from the compactly arranged devices without requiring increased spacing, thus maintaining miniaturization while improving thermal management.

The patent divides the signal conversion process into multiple stages using separate optoelectronic devices for different functions (e.g., separate devices for modulation, transmission, and reception). This segmentation allows each device to be optimized for its specific function at high speeds while maintaining overall conversion reliability through the coordinated operation of specialized components.

The patent assigns different functional characteristics to different optoelectronic devices within the module. Each device is optimized with specific local properties (e.g., different materials, structures, or operating parameters) suited to its particular signal conversion task, enabling high transmission rates while maintaining reliability through specialized optimization at each stage of the conversion process.
