Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems are inadequate for handling the high bandwidth demands of modern internet and mobile applications, particularly in transferring multimedia files, due to limitations in electrical components and channel bandwidth, which leads to inter-symbol interference and the need for improved data transfer methods beyond Moore's Law.
Innovation Solution
A high-speed electrical optics multiple chip module device is proposed, utilizing silicon photonics to integrate optical devices close to electrical components, enabling terabit-per-second speeds through a single-chip system-on-a-chip configuration with features like Serializer/Deserializer blocks, clock data recovery, and forward error correction, optimized for spine-leaf network architectures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If electrical components and channel bandwidth are increased to handle high data transfer demands, then data transfer speed improves, but inter-symbol interference increases and system reliability deteriorates
Solution Approach 1:
The patent replaces electrical signal transmission with optical signal transmission using silicon photonics. Optical signals are immune to inter-symbol interference that plagues electrical signals at high speeds, thereby maintaining signal integrity while achieving terabit-per-second data transfer rates. The optical communication interface substitutes the electrical channel with an optical channel that does not suffer from the same bandwidth limitations and interference issues.
2Productivity
If multiple chip modules are used to increase bandwidth, then data transfer capacity improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the electrical communication interface and optical communication interface onto a single silicon substrate, creating an integrated system-on-chip. This consolidation combines multiple previously separate chip modules into one unified device, achieving high bandwidth while reducing device complexity and manufacturing cost. The integrated design eliminates the need for separate electrical and optical chips, simplifying the overall system architecture.
Solution Approach 2:
The silicon substrate serves multiple functions simultaneously: it acts as both the electrical communication interface and the optical communication interface platform. The single chip performs both electrical signal processing and optical signal generation/detection, providing multi-functionality that reduces the number of separate components needed and simplifies the system while maintaining high bandwidth capability.
3Reliability
If electrical components are placed closer to reduce inter-symbol interference, then signal quality improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent eliminates the need for close placement of electrical components by substituting electrical signal transmission with optical signal transmission. Optical signals can travel through waveguides over longer distances without suffering from inter-symbol interference, allowing components to be placed further apart while maintaining signal quality. This reduces the stringent manufacturing precision requirements associated with sub-micron component placement.
