Silicon photonics to capture almost $4 billion of optical transceivers market by 2025

Silicon photonics is on the verge of experiencing dramatic uptake in optical transceivers, market research firm Yole Développement has reported, with the technology set to capture 35 per cent – almost $4 billion – of the optical transceiver market by 2025, up from just a few per cent in 2016.

The transceivers are expected to be used mostly for intra-data centre communication, according to Yole, with the strongest demand being for 400G (400 Gigabits per second), and 200G acting as an intermediate step between 100G and 400G.

Mellanox ceases 1550nm silicon photonics development

Mellanox Technologies is stopping development of its 1550nm silicon photonics technology and products, effective immediately. About 100 people will lose their jobs as a result.

Mellanox gained its silicon photonics activities through the 2013 acquisition of Kotura in a deal valued at $82 million. The start-up had developed a line of variable optical attenuators (VOA) in silicon photonics, and believed that its technology showed great promise to drive down the cost of high-speed interconnect products.
