1. Industry Positioning: Optical chips, the core segment with the highest technical barriers and value in the optical communication industry chain, are the performance cornerstone of optical communication systems. They determine the quality, speed, and energy efficiency of optical signal transmission, and are the key components with the highest technical barriers and added value in optical modules. 2. Technology Path: Silicon photonics solutions are accelerating their penetration, and the light source is switching from EML to CW. Traditional discrete solutions face bottlenecks at 1.6T and higher speeds, driving increased adoption of highly integrated, low-cost silicon photonics solutions. This promotes a structural shift in light sources: from EML chips suitable for discrete solutions...
