Ace Photonics Co., Ltd

Changchun ACE PHOTONICS Co, Ltd.(referred to as ACE PHOTONICS) was established on September 30, 2018. It was jointly funded by the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, and strategic investors. It mainly engages in vertical-cavity surface-emitting lasers (VCSEL) R&D and produces laser chips and modules. VCSELs are optoelectronic devices that combine the performance of traditional semiconductor lasers with the cost savings of LEDs. Unlike traditional edge-emitting lasers, VCSELs emit optical power from the surface of a wafer or chip. This enables wafer probing before chip sorting and packaging. In addition, VCSELs exhibit excellent wavelength stability over temperature and can be used with infrared bandpass filters to remove additional background noise from the received signal.
