Lightmatter Aims to Bridge Chiplets With Photonics

The demise of Moore’s Law has been much debated among engineers and experts at this point. Also, as silicon-based transistors got smaller and smaller, manufacturers had to contend with increased temperature density (more transistors in a smaller area generates more heat).

And even though chiplet technologies such as TSMC’s InFO_LI and Intel’s Foveros 3D technology have improved their capabilities and allowed multiple chips to be paired within the same board, connecting these chips together is , requires a wire carrying electrons. Flying electrons mean higher temperatures (by passing through the resistance of the semiconductor) and increased power covered in register, the startup Lightmatter has another idea. The idea is to connect chips without using any electrical wiring at all. The company has embraced HotChips in photonics as an alternative.
