The rapid expansion of AI data centers and the intensifying race for AI computing power are accelerating the transition toward transmission speeds above 1.6 Tbps, according to TrendForce’s latest research. Major players such as NVIDIA, Google, and Meta are securing a stable supply by strategically locking in production capacity from electro-absorption modulated laser (EML) and continuous-wave distributed feedback laser diode (CW-DFB LD) suppliers. This has prompted suppliers to aggressively expand capacity in response to customer demand, doubling the comb...

Sumitomo Electric has successfully developed Flexible Printed Circuit (FPC) for LED applications that can tolerate high temperature of 150 degrees Celsius, according to a report by Nikkei.

Major step in joint partnership to develop market of GaN substrates for high-performance LED lighting applications. Soitec (Euronext), a world leader in generating and manufacturing revolutionary semiconductor materials for the electronics and energy industries, and Sumitomo Electric Industries, Ltd., a leading worldwide provider of compound semiconductor materials, have signed a licensing and technology-transfer agreement under which Sumitomo Electric will use Soitec’s proprietary Smart Cut™ technology to manufacture engineered gallium nitride (GaN) substra...

Recently, Japan's Sumitomo Electric Industries Ltd. is said to develop the world’s first 6-inch diameter gallium nitride (GaN) substrates for white LEDs. Presently, the white LED market has been growing using 2- to 4-inch sapphire substrates. As an alternative to sapphire, Sumitomo Electric began production of 2-inch diameter GaN substrates designed for use in white LEDs.
