POET announces availability of 400G and 800G receive optical engines

POET Technologies Inc of Toronto, Ontario, Canada — a designer and developer of the POET Optical Interposer and photonic integrated circuits (PICs) for the data-center, telecom and artificial intelligence (AI) markets — has started sampling 400G FR4 and 800G 2xFR4 receive optical engines (RXOEs). POET will partner with Luxshare Technology Co Ltd (a subsidiary of Luxshare Precision Industry Co Ltd of Dongguan, China, that designs and manufactures datacom facilities and enterprise-level products) as a lead customer to enable the sale of power-efficient and cost-optimized 400G and 800G transceiver solutions.

“LuxshareTech is focused on expanding its 400G and 800G pluggable transceivers portfolio for the data-center market,” says Mike Gao, general manager of LuxshareTech’s Opto-electronic business unit. “We are pleased to work with POET Technologies and use their highly integrated chiplet platform to enable us to achieve a solution with superior performance and ease of compact module assembly,” he adds.

“The 400G and 800G FR4 RXOEs are the first of their kind to integrate photonic and electronic components on a single interposer chiplet,” says Raju Kankipati, VP of product management at POET. “We expect customers to benefit from the simplified design, superior performance and lower cost offered by POET’s wafer-scale integration and passive assembly of components,” he adds. “LuxshareTech’s experience in designing and manufacturing high-speed optical transceivers and POET’s innovative technology can be mutually beneficial in bringing high-volume and low-cost solutions to the data-center market.”

Produced by POET’s joint venture Super Photonics Xiamen, the 400G FR4 RXOE integrates a quad trans-impedance amplifier (TIA), four high-speed photodiodes and an optical demultiplexer integrated in a single chiplet measuring 12x5mm. The 800G 2xFR4 RXOE consists of an integrated octal TIA, eight high-speed photodiodes and two optical demultiplexers in a single chiplet measuring 15x5mm.

Customers of POET’s RXOEs have the option to procure the engines with an integrated fiber array unit (FAU), which provides an even more complete solution for next-generation data-center interconnects. The 400G and 800G RXOEs achieve superior performance through better integration of photodiodes and TIA and exceed the industry-standard specifications for 400GBASE-FR4 interfaces.

POET expects to complete design verification testing and reliability qualification of the RXOEs in first-half 2023 and to start production in second-half 2023.
