Understand this story
Zhejiang Huachen Xinguang has developed a single-mode 980nm pump laser chip using its proprietary WXP facet passivation process, and is entering this product in the 8th IC Trend List Annual Technology Breakthrough Award. According to Jiwei.com, the process raises the catastrophic optical damage threshold by more than 500%, with the chip's slope efficiency exceeding 1.0W/A and multimode 9xxnm chips exceeding 1.2W/A, and reliability lifetimes 5-10 times longer than those of conventional processes. The report also states that the chip is the first to complete mass-production validation, filling a domestic gap, and that the company has obtained 22 invention patents and 38 utility model patent authorizations. There is currently no qualified factual evidence of the award selection result or other follow-up developments.
