POET Technologies Announces Availability of Samples of its 100G and 200G CWDM4 Optical Interposer-based Engines

June 8th, 2021

TORONTO, Ontario, June 8, 2021 – POET Technologies Inc. (“POET” or the “Company”) (TSX Venture: PTK; OTCQX: POETF), the designer and developer of integrated optical engines for the optical communications, computing and sensing markets, all based on the POET Optical Interposer™, announces that samples of its 100G and 200G CWDM4 Optical Engines will be available beginning in early July.

Powered by four flip-chipped 28G and 28G PAM4 CWDM (course wavelength division multiplexed) DFB (distributed feedback) lasers, the POET Optical Engines include an integrated athermal multiplexer and demultiplexer, 28G detectors, monitor photodiodes and bonding pads. Operating to MSA (Multi-Source Agreement) standards for the QSFP28 module, the POET Optical Engines will be available in chip sets for transmit only, receive only or in a combination transmit and receive single multi-chip engine less than 60mm square.

Built on a high resistivity 8” silicon wafer with low-loss, athermal waveguides, POET’s Optical Engines include passively-aligned active devices and superior thermal management.  These engines offer best-in-class coupling efficiencies, including to fiber attach units, and operate over a range of 500m to 10km under ambient operating temperatures of 0°C to 70°C. 

Based on the novel POET Optical Interposer platform, the 100G and 200G Optical Engines are fabricated entirely at wafer scale, offering unparalleled cost and size advantages. All engines are fully tested and burned-in prior to shipment. Super Photonics Xiamen, POET’s joint venture with Sanan IC, will be manufacturing the optical engines, with the capability to rapidly scale for customers with high-volume requirements.

POET will also soon be offering 400G DR4 and FR4 transmit and receive optical engines.  Samples of the receive optical engine will be available in September.  Samples of the transmit engine, based upon high power CW (continuous wave) lasers and silicon photonic modulators, will be available beginning in Q4 2021.

Live demonstrations of POET products are being conducted by the Company during the virtual Exhibition at the Optical Fiber Conference (OFC) taking place from Monday through Friday, June 7 – 11, 2021. For additional information or a demonstration, interested parties may contact Vivek Rajgarhia, the Company’s President & General Manager at the following email address:  [email protected].

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.

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 planned 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, a delay or abandonment of its planned 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, and the ability to raise additional capital. Although the Company believes that the expectations reflected in the forward-looking information or statements are reasonable, prospective investors in the Company’s securities should not place undue reliance on forward-looking statements because the Company can provide no assurance that such expectations will prove to be correct.
