POET TECHNOLOGIES ANNOUNCES SAMPLING OF 200G FR4 TRANSMIT AND RECEIVE OPTICAL ENGINES FOR QSFP56 TRANSCEIVERS FOR CLOUD DATA CENTERS AND 5G CONNECTIVITY

Poet Technologies Inc. has sent samples of its 200G FR4 transmit (TX) and receive (RX) optical engines. The Optical engines are based on the Poet Optical Interposer, a unique hybrid integration photonics packaging platform.

The company has shipped samples to multiple lead customers through Super Photonics, its joint venture with Sanan IC, and expects the 200G FR4 TX and RX optical engines to be in production at Super Photonics by the end of 2022.

The 200G FR4 transmit optical engine integrates four high-speed directly modulated lasers (DMLs), each operating at 50-gigabit-per-second speed with a low-loss AWG-based (arrayed waveguide grating) multiplexer that is monolithically integrated on the Optical Interposer. Monitor photodiodes are built into the optical engine for active power monitoring.

The 200G FR4 receive optical engine integrates four high-speed photodetectors each operating at 50-gigabit-per-second speed with a low-loss AWG-based demultiplexer that is monolithically integrated on the Optical Interposer. A single mode optical fibre with LC connector is attached to the TX and RX optical engines for seamless integration in a 200GBASE-FR4 transceiver module.

"We see significant customer interest in 200GBASE-FR4 transceivers and are excited to start sampling our optical engines for this application," said Raju Kankipati, vice-president of product line management (PLM) at Poet Technologies. "Our highly integrated optical engines will enable customers to offer cost-effective and scalable 200GBASE-FR4 and 2x200GBASE-FR4 transceivers to cloud data centre end customers. We, through our joint venture, Super Photonics, have started sampling multiple lead customers, who we expect to work closely with through their transceiver design completion phase."

200G FR4 transmit and receive optical engine key features:

• Supports 200GBASE-FR4 PAM-4 transmission;
• Uncooled DFB lasers (CWDM wavelengths) and PIN photodetectors;
• A low-loss AWG-based quad-wavelength multiplexer and demultiplexer that are temperature independent and monolithically integrated into the optical waveguide layer of the Optical Interposer;
• A small-size form factor, which enables a 200GBASE-FR4 and 2x200GBASE-FR4 in a QSFP56 optical transceiver module;
• LC connectorized single mode fibre attached to the engines.

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.

We seek Safe Harbor.
