POET TECHNOLOGIES ANNOUNCES AVAILABILITY OF 400G FR4 AND 800G (2X400G FR4) RECEIVE OPTICAL ENGINES FOR QSFP-DD AND OSFP TRANSCEIVERS FOR CLOUD DATA CENTERS

Poet Technologies Inc. has made available its 400G FR4 and 800G (two 400G FR4s) receive (RX) optical engines based on the Poet optical interposer, a unique hybrid integration photonics packaging platform.

The company has shipped samples to multiple lead customers and expects the 400G FR4 receive optical engine to be in production at Super Photonics, its joint venture with Sanan IC, by the end of Q3 2022. The 400G FR4 receive optical engine integrates four 56-gigabaud photodetectors each operating at a speed of 100 gigabits per second with a low-loss AWG-based (arrayed waveguide grating) demultiplexer that is monolithically integrated on the optical interposer. A single-mode optical fibre with LC connector is attached to the optical engine for seamless integration in a 400GBASE-FR4 transceiver module.

"We are excited to announce the completion of design, verification testing and availability of preproduction parts for customers to take advantage of our highly integrated optical engines to build 400G FR4 and 800G (two 400G FR4s) transceivers," said Vivek Rajgarhia, president of Poet Technologies. "Our small form factor and easy-to-integrate optical engine enables cost-effective and scalable solutions for cloud data centres. Customers can integrate a single receive engine or dual engines in a QSFP-DD or OSFP pluggable transceiver form factor to achieve a 400GBASE-FR4 or 800G (two 400GBASE-FR4s) solution. The shipping of 400G receive samples marks a significant milestone for the company as we continue to commercialize multiple products and align them with the needs of customers."

400G FR4 receive optical engine key features:

• Four 56-gigabaud photodetectors each operating at a speed of 100 gigabits per second, flip chipped onto the optical interposer and coupled passively to vertical mirrors embedded in the optical interposer;
• A low-loss AWG-based quad-wavelength demultiplexer that is polarization independent and temperature independent and is monolithically integrated into the optical waveguide layer of the optical interposer;
• A small-size (3.8 millimetres by 10 millimetres) form factor, which enables an 800G optical engine in a configuration of two 400Gs in both QSFP-DD800 and OSFP optical transceiver modules;
• LC connectorized single-mode fibre attached to the optical engine.

About Poet Technologies Inc.

Poet Technologies is a design and development company offering integration solutions based on the Poet optical interposer, a novel platform that allows the seamless integration of electronic and photonic devices into a single multichip module using advanced wafer-level semiconductor manufacturing techniques and packaging methods. Poet's optical interposer eliminates costly components and labour-intensive assembly, alignment, burn-in and testing methods employed in conventional photonics. The cost-efficient integration scheme and scalability of the Poet optical interposer brings value to any device or system that integrates electronics and photonics, including some of the highest-growth areas of computing, such as artificial intelligence (AI), the Internet of things (IoT), autonomous vehicles, and high-speed networking for cloud service providers and data centres. Poet is headquartered in Toronto, with operations in Allentown, Pa., Shenzhen, China, and Singapore.
