China-based San’an Optoelectronics is collaborating with Tsinghua University and China Mobile to develop microLED-based optical communication solutions.
San'an has recently successfully developed a microLED based device with high-speed modulation capability. It is reported that the company's tests have demonstrated a 3dB modulation bandwidth exceeding 7 GHz. Based on communication models, San'an's NRZ-OOK data transmission rate is expected to surpass 10Gb/s/.
San'an Optoelectronics is China's largest LED epitaxial wafers and chips producer, making over 24 million wafers annually - almost 60% of China's total production. The company has been involved with microLED technologies for many years, working with Samsung, TCL CSoT, and others.
In 2019 San'an announced plans to setup a $1.8 billion Mini-LED and Micro-LED production center in Hubei, China. In 2025, San'an increased its microLED production capacity to 1,400 monthly 6" wafers.
In August 2025, San'an announced that it is set to acquire Netherlands-based LED producer Lumileds, for $239 million in cash. Towards the end of 2025 San'an announced that it is progressing with its microLED products for AR applications, and is moving from the technology verification state, to the small-batch verification stage.
