POET TO DEMONSTRATE CUTTING-EDGE LIGHT SOURCE AND INDUSTRY-LEADING 1.6T OPTICAL ENGINES FOR AI APPLICATIONS AT OFC CONFERENCE

Poet Technologies Inc. plans to demonstrate its latest technology innovations and products at the Optical Fiber Communications (OFC) Conference, which will be held in San Francisco, Calif., from April 1 to April 3, 2025. Poet's executive management team and engineers will be meeting customers and industry analysts at the company's booth No. 5315 during the exhibition.

Poet Blazar demo (invitation only): Senior technical and executive management of select technology companies will have the opportunity to observe the highly anticipated Poet Blazar prototype in private meetings with Poet management. Built on the Poet Optical Interposer platform, Blazar is a ground-breaking light source solution to power both co-packaged optics (CPO) and high-bandwidth, chip-to-chip, light-based data communications links. Named after an extremely bright galactic object, Blazar utilizes Poet's wafer-level chip-scale packaging technology to create a high-power, multichannel light source as an alternative to traditional DFB (distributed feedback) laser-based solutions. Wafer-level chip-scale technology significantly lowers the cost of the light source, provides larger scale and better reliability, and promises to increase the effective supply of indium phosphide, a rare and limited compound semiconductor material commonly used as the light-producing element in lasers.

"Given the vast potential of our ELS (external light source) solution and the sensitive nature of the technology, we have opted to limit its exposure, which is why we are selecting a number of senior technologists and executives to an invitation-only viewing," said Poet chairman and chief executive officer Dr. Suresh Venkatesan. "The Blazar can transform the economies of scale for [artificial intelligence] connectivity with an architecture that reduces costs, and increases scale and manufacturing efficiency. With the massive amount of compute power that AI demands, we believe that the Blazar offers an economically superior solution to achieving next-generation performance. It is a crucial component to getting to 3.2T in pluggable optical modules, and achieving the higher speeds, bandwidth and low latency needed for chip-to-chip data communication links."

Poet Teralight 1.6T optical engine (live public demo): In partnership with Mitsubishi Electric, Poet will unveil its Teralight product line of 1.6T highly integrated transmit and receive optical engines offering a complete optical system-on-chip architecture that reduces cost and simplifies module design. The 1.6T transmit engine includes only four externally modulated laser chips, rather than the standard eight lasers for 1.6T transceivers, due to Mitsubishi Electric's unique two times 200G EML (electroabsorption modulated laser) design, a cost reduction in the most expensive transmit component. Built-in high-speed drivers, monitor photo diodes, a thermistor and optical multiplexers (for FR4 (flame retardant 4) applications) make this the most highly integrated system on chip available on the market. The receive engine includes photo diodes, transimpedance amplifiers (TIAs) and demultiplexers (for FR4 applications). The Poet Optical Interposer design eliminates the use of wire bonds between devices, which reduces the RF (radio frequency) crosstalk to achieve industry-leading performance at the highest speeds available on the market. The system-on-chip architecture allows customers to use the same board design for 1.6T DR8 and two times FR4 pluggable modules, a feature unique to Poet that eliminates the need for separate DR and FR engineering teams, which has been a standard development approach within the industry.

Leading module customers incorporating Poet optical engines: Among the leading suppliers offering modules based on Poet's optical engines, LuxshareTech will be demonstrating 400G and 800G DR and FR modules at OFC (booth No. 4905), and Adtran (formerly ADVA) will demo a highly integrated Quattro 100G LR4 in its private demo room. Quattro LR4 integrates four instances of 100G LR4 into a single QSFP-DD (quad small form factor pluggable double density) form factor, quadrupling the density of 100G ports in 400G switch and routing platforms. This module has gained intense interest from both hyperscalers and telecom network providers for its performance and cost-effectiveness.

• Product showcase: Poet will also have a product showcase of its current portfolio suite of optical engines and light sources at its booth. Some of those products have been designed into customer solutions that will be demonstrated at the Poet booth as market-ready applications.
• Lightwave award: In addition, company representatives will collect the recently announced elite score award at the Lightwave+BTR Innovations Reviews Reception, which is scheduled to be held at the Moscone Center in rooms 307/308 on March 31, 2025, at 5 p.m. PST.
