POET Technologies and Mitsubishi Electric to develop optical chipsets for 3.2T transceivers

POET Technologies, the Toronto photonics specialist, is to collaborate with Mitsubishi Electric to co-develop integrated optical engine chipsets for 3.2T pluggable transceivers.

“We believe POET’s optical engines will open the possibility of creating new products where electronics photonics convergence is successfully achieved at an advanced level of integration between InP and Si-based interposer, which take us into the next generation of data networking for AI and hyperscale data centers,” says Yasuhiro Yamauchi, General Manager, Optical Device Department at Mitsubishi Electric.

Mitsubishi will contribute its 400G Electro-absorption Modulator integrated Lasers (EMLs) to the project. Using its optical interposer platform technology, POET will integrate the EMLs along with drivers, optical waveguides, and other key functional building blocks to produce 1.6T and 3.2T optical engine chipsets.

“The AI and datacom networks need a pluggable transceiver solution for 3.2T and POET’s optical interposer is one of the few technologies that can achieve that performance,” says POET CEO Suresh Venkatesan, “when  our Mitsubishi Electric colleagues understood the full functionality of the optical interposer and its potential to optimize the performance of their lasers, they knew that we offered the right solution for their needs.”

POET and Mitsubishi Electric aim to complete the 1.6T and 3.2T optical engine chipsets in early 2025 and then demonstrate the innovation during the first half of that year.
