What Yuanjie Semiconductor does

Yuanjie Semiconductor Technology Co., Ltd. (陕西源杰半导体科技股份有限公司, stock code: SSE 688498) is a Shaanxi, China-based semiconductor company founded in 2013 by Zhang Xingang (Tsinghua and USC-educated). It designs and manufactures high-speed Indium Phosphide (InP) laser chips — specifically Distributed Feedback (DFB) lasers and Electro-absorption Modulated Lasers (EMLs) — at data rates from 2.5G to 50G+, serving FTTH/PON, 5G wireless fronthaul, AI data center optical interconnects, and automotive LIDAR applications. The company operates a full Integrated Device Manufacturer (IDM) model with independent intellectual property spanning MOCVD epitaxial growth, chip design, wafer fabrication, and automated testing, purchasing only substrates and gas sources externally.

The company's revenue is generated primarily through direct B2B sales of laser chip components to optical module manufacturers, data center operators, and telecom equipment companies, with quote-based per-order pricing and no public list. Its 2025 revenue reached approximately $87M (620M yuan), up 138.5% YoY, driven by a 719% surge in data center segment revenue to ~$56.9M as AI infrastructure buildouts drove demand for high-speed optical interconnects. Net profit grew over 32x YoY to 191M yuan. The company is publicly listed on Shanghai's STAR Market since December 2022, backed by Huawei and Shaanxi state-owned assets (Zhongji Xuchuang holds ~3.82%), and is pursuing a Hong Kong H-share listing for international expansion. Its market capitalization reached ~94.6B yuan (~$13.7B) by April 2026, making it mainland China's highest-priced stock.
