Technology Semiconductors

POET Technologies Inc. is a design and development company. It offers high-speed optical engines, light source products and custom optical modules to the artificial intelligence (AI) systems market and to hyperscale data centers. Its photonic integration solutions are based on the POET Optical Interposer, a novel, patented platform that allows the integration of electronic and photonic devices into a single chip using wafer-level semiconductor manufacturing techniques. Its Optical Interposer-based products consume less power than comparable products, are smaller in size and are readily scalable to high production volumes. In addition, it has designed and produced novel light source products for chip-to-chip data communication within and between AI servers, the next frontier for solving bandwidth and latency problems in AI systems. Its Optical Interposer platform solves device integration challenges across a range of communication, computing and sensing applications.

RE:Interesting

Aug 15, 2023 - Enhancements to the Optical Interposer now support 200Gbps per lane speed for both the transmitter and the receiver. The transmit optical engine has been modified for externally modulated lasers (EML), EML drivers and monolithically integrated multiplexers for single mode fiber applications for up to 10km reach. The receive optical engine can now incorporate the next generation higher speed photodiodes, trans-impedance amplifiers and monolithically integrated low-loss polarization-insensitive demultiplexers for 1.6T transceivers and beyond.

"So this begs the question, what are the issues here as they pursue the 800G+ market? What happens to POETs advantages, Scalability, Cost and Performance advantages? How quickly can they modify the POET interposer?"

There's an element of contrition in this letter. Why?

POETs advantage, admittedly only by management, has always been about Scalability, Cost and Performance Advantages......one thing never alluded to but finally noted in this letter is ADOPTABILITY.

We see now that POET doesn't have revenue because its having difficulty getting the industry to adopt its technology. The only path forward was a JV with SPX in China. Even this path would lead to limited adoption by only "niche" players, as noted in the letter. Moreover, it had no future beyond the 100, 200 and 400G optical engines.

So what now? Suresh in order to be relevant going forward, POET needs to modify and adapt to EMLs which is the industry standard. POET uses DMLs for the 100, 200 and 400G engines but it turns out EML are better suited for higher speeds, 800G and beyond. Doesn't this remind everyone of the GaAs fiasco.

So this begs the question, what are the issues here as they pursue the 800G+ market? What happens to POETs advantages, Scalability, Cost and Performance advantages? How quickly can they modify the POET interposer?

Its as if we are now back to square one, with all the inherent risks and unknowns.
This letter is like a revelation of the risks associated with holding this investment. An I told you so letter, in case things may not work out. IMHO
