Aeluma's stock already prices in much of a successful FY28-FY29 commercialization, while commercial revenue is minimal and no volume customers are publicly named. Its III-V-on-silicon technology is real, but of $2.657M in revenue for the six months to December 2025, only $41k came from non-government work, and Q2 revenue fell year over year. Most of its 20+ customer engagements are still in evaluation or prototyping, and government contracts de-risk the physics, not adoption. x.com 

Aeluma's quantum dot technology is years too early, so investing now mostly funds dilution for R&D. A Goldman Sachs note sees MicroLED far from any co-packaged optics volume ramp and does not even mention quantum dots. Even with product ready in Q4 2026, sampling and qualification could push volume to 2029, and Aeluma may end up like POET in 2025 with constant share sales. In a correction, only revenue backs valuations; Sivers and Applied Optoelectronics ramp CW laser volume within months. x.com  … Show more

Aeluma is a speculative small cap with a rare ability to put compound semiconductors on standard 200mm and 300mm silicon, making quantum dot lasers, nonlinear photonics and detectors that feed CPO, VCSELs and quantum photonic ICs. A seed investor is Shuji Nakamura, the Nobel laureate who co-invented the blue LED. Catalysts include $4M+ in government contracts, Tower Semi and Sumitomo partnerships, and DARPA, NASA and Navy customers. Risks are a $50M ATM, heavy insider selling and no revenue yet. … Show more

Aeluma looks more like a university project than a company, so its price has been badly speculative without reason. If its technology proves useful, it will likely be acquired, but it does not merit more time or effort. x.com  x.com 

Aeluma's technology is ready but meaningful revenue is still far off, so it is a wait-and-see stock until a signed purchase order arrives. Q3 revenue of $1.2M missed the $1.35M consensus and FY2026 guidance narrowed to $4.2-4.6M, blamed on government contract delays. It grows quantum-dot lasers on 200mm silicon with MOCVD and has moved production to Tower Semiconductor, but H2 2026 is for sampling and yields; problems in the first qualification could add long delays. x.com  x.com 

Aeluma is in almost the same setup as Lightwave Logic before its big run, after winning over $4M in US government contracts for quantum dot lasers and quantum nonlinear materials with Tower Semiconductor as manufacturing partner. Lightwave Logic, small and pre-revenue with Tower and government validation, rose 138% in a month. Aeluma's lasers target AI data center links as speeds push toward 3.2T. It is even earlier stage, so upside is larger if the technology converts, but risk is high. x.com 

AI photonics is the next scarce layer after GPUs and memory, with demand exceeding supply until mid-2027 as copper hits its wall at 1.6T. Indium phosphide wafers rose from about $1,400 to $5,000 after China's export licensing, supply covers under 30% of demand, and new lines are 2-3 years away. Applied Optoelectronics makes its lasers in-house in Texas, Lumentum's five InP fabs trail demand by over 30%, Coherent grows its own InP, and Credo gets paid on both copper and optical links. x.com  x.com  … Show more

Coherent is the most potentially undervalued photonics play because the market has not caught up to what it has become. Its March 23 demonstration with Tower Semiconductor of 400 Gbps per lane on a silicon modulator, aimed at 3.2T transceivers, is not priced in. Revenue rose from $1.58B to $1.69B with $1.78B guided, and it was first to mass-produce 1.6T transceivers. Despite running from $61 to $336, it trades at a fraction of Arista's and Broadcom's valuations. x.com  x.com 

Rising 1.6T switching demand favors optical suppliers, though their execution risks vary. Bank of America says the market could grow ~101% annually through 2030. Marvell's leading DSPs and Lumentum's supply-short 200G EML lasers are lowest risk; Applied Optoelectronics' capacity expansion and Fabrinet's customer concentration make them medium risk. Aeluma remains pre-commercial, while Lightwave Logic's polymer modulators are a high-risk moonshot despite its TSM partnership. x.com 

The Tema Photonics & Optical ETF is hard to beat as a way to invest in photonics, whose AI data-movement market Goldman Sachs forecasts will grow about 9x between 2026 and 2028. The actively managed fund is run in research partnership with SemiAnalysis, with top holdings including Lumentum, Aixtron, AXT, Applied Optoelectronics, Furukawa Electric, Zhongji Innolight, Tower Semiconductor, Aehr Test Systems and Sivers Semiconductors. x.com
