Founded in 2001, GLsun focuses on the development of semiconductor full process technology platform for the industrialization of optical chips, including optical chip simulation design, Epitaxial growth MOCVD, Grating manufacturing, Dielectric film deposition, Nano photoetching, Metal evaporation, Chip thinning, Mirror coating, Cleavage test, Chip packaging, etc and other dozens of manufacturing procedures. GLsun has mastered the core key technology of each process, has epitaxial growth MOVCD technology and quantum well nanotechnology, and has grasped domestic leading manufacturing processes such as 3-inch holographic exposure grating. We can not only develop and manufacture independently, but also undertake all stages of OEM from design to manufacture. Independent R&D and production and opening-up services have effectively filled the domestic gap in this field.
With widely production portfolio, our products including DFB/VCSEL LD chips (2.5G~25G), MPD, PIN/PD, APD chips ( 2.5G-25G), TO-CAN (TO46/TO56/TO38), 20 years raw manufacture experiences of high data rate passive optical devices and modules (FSI/optical switches/CWDM/DWDM/Cirtulators/bypass modules), customer designed modules, transmission, monitoring and system protection equipment,etc.
Passed ISO9001, ISO14001, RoHS, GLsun offers high quality products and services for well-known enterprises at home and abroad, enjoying a good reputation and high brand awareness in the industry.
