POET Technologies Announces Sampling of 200G FR4 Transmit and Receive Optical Engines for QSFP56 Transceivers for Cloud Data Centers and 5G Connectivity

July 6, 2022

Toronto, Ontario, July 6, 2022 – POET Technologies Inc. (“POET” or the “Company”) (TSX Venture: PTK; NASDAQ: POET), the designer and developer of the POET Optical Interposer™ and Photonic Integrated Circuits (PICs) for the data center and tele-communication markets, today announced sampling 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 Gigabits/second speed with a low-loss AWG (Arrayed Waveguide Grating)-based 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 Gigabits/second speed with a low-loss AWG (Arrayed Waveguide Grating)-based demultiplexer that is monolithically integrated on the Optical Interposer. A single mode optical fiber 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, VP 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 center 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 (4x50Gbps) PAM-4 transmission
  • Uncooled DFB lasers (CWDM wavelengths) and PIN photodetectors
  • A low-loss AWG (Arrayed Waveguide Grating)-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 an 200GBASE-FR4 and 2x200GBASE-FR4 in a QSFP56 optical transceiver module
  • LC connectorized single mode fiber attached to the engines

Such statements include the Company’s expectations with respect to the success of the Company’s product development efforts, the performance of its products, the expected results of its operations, meeting revenue targets, and the expectation of continued success in the financing efforts, the capability, functionality, performance and cost of the Company’s technology as well as the market acceptance, inclusion and timing of the Company’s technology in current and future products and expectations for approval of proposals at the Company’s annual meeting of shareholders.

Such forward-looking information or statements are based on a number of risks, uncertainties and assumptions which may cause actual results or other expectations to differ materially from those anticipated and which may prove to be incorrect. Assumptions have been made regarding, among other things, management’s expectations regarding the success and timing for completion of its development efforts, financing activities, future growth, recruitment of personnel, opening of offices, the form and potential of its joint venture, plans for and completion of projects by the Company’s third-party consultants, contractors and partners, availability of capital, and the necessity to incur capital and other expenditures. Actual results could differ materially due to a number of factors, including, without limitation, the failure of its products to meet performance requirements, lack of sales in its products, once released, operational risks in the completion of the Company’s anticipated projects, lack of performance of its joint venture, delays in recruitment for its newly opened operations or changes in plans with respect to the development of the Company’s anticipated projects by third-parties, risks affecting the Company’s ability to execute projects, the ability of the Company to generate sales for its products, the ability to attract key personnel, the ability to raise additional capital and the agreement by shareholders to approve proposals put forth by the Company at shareholders’ meetings.
