Optical semiconductor products supplier Raysees raised angel funding last year from investors including CAS Star, a Chinese Academy of Sciences affiliate.

Raysees, a China-based optoelectronic parts developer backed by an affiliate of Chinese Academy of Sciences (CAS), has received an eight-figure renminbi (RMB10m = $1.4m) pre-series A sum from investors led by venture capital firm Shenzhen Capital Group, China Money Network reported yesterday.
The round also included investment firm Ivy Capital and venture capital firm Elevation China Capital.
Raysees produces optical semiconductor technologies used by manufacturers to construct optoelectronic chips that could provide superior data transmission capacity and energy efficiency compared with conventional equivalents.
The company’s offering includes a vertical-cavity surface-emitting laser (VSCEL) – a form of semiconductor laser diode useful for optical fibre communications whose production in China is reportedly hindered by various bottlenecks.
Raysees also markets optical components specifically tailored to optoelectronic chip-powered technologies including artificial intelligence, assisted driving, smart logistics and health-focused sensors.
The business was founded in 2018 and went on to secure an eight-figure renminbi (RMB10m = $1.5m) amount later that year from CAS Star – an investment arm affiliated with CAS – in addition to Elevation China Capital.
