POET Readies Optical Interposer for Production in Alignment with Product Roadmap

October 29th, 2020

New Optical Interposer Features Added to Prototypes

TORONTO, Ontario, October 29, 2020 – POET Technologies Inc. (“POET” or the “Company”) (TSX Venture: PTK; OTCQX: POETF) a leading designer of Photonic Integrated Circuits (PICs) for the data center and tele-communication markets, announced today that it has added several new features to its proprietary POET Optical Interposer™ platform and completed the design for products identified on its roadmap.

New Optical Interposer features include:

  • waveguide designs and process integration methods that minimize reflections of laser light within the Optical Interposer platform;
  • fiducials that better enable the sub-micron accuracy of automated pick-and-place assembly of lasers and other components mechanically placed on the platform;
  • vertical mirrors that extend the platform applicability to top- and bottom-surface-access optical devices, such as top-entry photodetectors and vertical cavity surface emitting lasers (VCSELs);
  • improved spot-size converters that provide efficient coupling of lasers and modulators to waveguides (important for 400G and 800G optical engines);
  • the latest generation of low-loss Mach-Zehnder Interferometry (“MZI”)-based multiplexers embedded in the waveguides; and
  • newly developed IP to efficiently align fiber-attach-units (FAUs) to POET’s optical engines.

“We have determined that the Optical Interposer platform is now production-ready,” said Vivek Rajgarhia, POET’s President & General Manager. “We have proven out all of the features and production methods for the platform itself, including the flip-chip assembly and bonding steps for lasers, which has historically been the “Achilles’ Heel” for other approaches to optoelectronic integration. The basic platform features, now completed, apply to all of the products that we are engaged with customers to develop.  The pre-Alpha and Alpha prototypes that are now being assembled differ primarily in the particular components included, and in most cases, those designs have been validated.”

Mr. Rajgarhia continued: “The POET Optical Interposer platform is fully compatible with standard CMOS semiconductor processing methods and equipment.  It seamlessly incorporates the best features of a Planar Lightwave Circuit (PLC), Silicon Optical Benches (SiOB) and Interposer functionality and is fabricated solely within the production limits of silicon-based semiconductor processing.  In addition to being fundamental to lower-cost and the higher-performance value proposition of the Optical Interposer, the processing compatibility with CMOS opens up a variety of applications to POET that are simply not available using other integration approaches seen in the market today.”

POET’s product roadmap, presented in its Annual General Meeting of Shareholders conducted in late August, revealed four products under development, each  associated with an individual customer or potential groups of customers.  The Company reported that the 100/200G CWDM4 Optical Engine, the 400G LightBar™, 400G FR4 Receiver, and the 400G FR4/DR Optical Engines all remain on schedule.

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, 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.
