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 restrict data transfer speeds and lead to inter-symbol interference.
Innovation Solution
The development of a high-speed electrical optics multiple chip module device, integrated on a single silicon substrate, utilizing silicon photonics to enhance data transfer rates beyond Moore's Law by moving optical devices closer to electrical components, incorporating a Serializer/Deserializer block, clock data recovery, compensation, and equalizer blocks, along with a driver module and receiver module, to achieve terabits per second speeds.

Engineering Contradiction Analysis
1Speed
If electrical components and channel bandwidth are used for data transmission, then data transfer can be achieved, but bandwidth limitations and inter-symbol interference occur which restrict data transfer speeds
Solution Approach 1:
The patent replaces electrical signal transmission with optical signal transmission. Optical devices (lasers, modulators, photodetectors) are integrated with electrical components on the same chip substrate, substituting electrical fields with optical fields for data transmission. This substitution eliminates bandwidth limitations and inter-symbol interference associated with electrical channels, enabling higher data transfer speeds while maintaining signal quality.
2Productivity
If optical devices are moved closer to electrical devices using silicon photonics, then data transfer rates increase beyond Moore's Law, but device integration complexity increases
Solution Approach 1:
The patent merges optical devices and electrical devices onto a single chip substrate, creating an integrated system. The optical components (light source, modulator, photodetector) and electrical components (signal processor, controller) are co-integrated on the same silicon chip, reducing inter-component distance and enabling terabits per second data transfer rates while managing integration complexity through unified substrate fabrication.
Solution Approach 2:
The chip substrate serves multiple functions simultaneously: it acts as the mounting platform for optical devices, the electrical circuit board for electrical components, and the integration medium that couples optical and electrical systems. This multi-functionality reduces the need for separate components and interfaces, thereby managing overall device complexity while achieving high data transfer rates.
3Speed
If multiple chip module technology is used to achieve high bandwidth, then data transfer speed improves, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple functional modules (optical devices, electrical components, signal processing units) onto a single chip substrate rather than using separate chips. This integration reduces the number of discrete components that need to be manufactured, assembled, and tested, thereby lowering manufacturing costs while achieving high data transfer speeds through optimized signal paths and reduced inter-component distances.
