The Tema Photonics & Optical ETF is the best way to own photonics, better than EUV and FOTO, as the only truly actively managed, institutional-quality photonics ETF. Its top holdings are Lumentum, AXT and Aixtron, and Tema partnered with SemiAnalysis to deliver pure-play exposure to leading-edge photonics and optics, a critical path in the AI buildout. Wall Street analysts see a $60 price target, 50% upside over 12 months. x.com 

The LYTE ETF offers pure-play exposure to global photonics and optics leaders, with Coherent and Lumentum as its top holdings. Nvidia CEO Jensen Huang has said the world needs substantially more silicon photonics capacity than it has today, explaining Nvidia's $4B investment in Lumentum and Coherent. x.com  x.com 

Tema Photonics & Optical ETF offers a way to hold a range of optical companies without trading the volatile individual names. Its roughly 9% exposure to an Anthropic SPV adds to the appeal. The ETF is thinly traded; the idea is to buy and hold for a year rather than keep trading. x.com  x.com 

Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com  x.com 

Co-packaged optics standards could make finished transceiver modules smaller and more interchangeable as chip designers build optical engines inside their packages. That is another reason to avoid Lumentum, Coherent and Applied Optoelectronics and prefer Soitec. Lumentum and Coherent now earn a lot from finished modules, leaving them exposed if the architecture changes. x.com 

Defiance's photonics ETF is a good tracker for photonics because it covers the whole supply chain, from indium phosphide to equipment, lasers and modules. Its top holdings fit: Lumentum is the best InP laser maker, AXT benefits as the InP shortage worsens, and Aixtron makes the MOCVD machines that produce lasers. Recent earnings showed the sector sold out, with long-term agreements removing cyclicality. Rival ETFs focus too narrowly on transceivers, so this suits a set-and-forget approach. x.com  … Show more

Photonics stocks remain attractive as AI optical-component demand exceeds supply: Lumentum's CEO says the company cannot meet 70% of demand for some products through 2027 or 30% for others through 2028, with some components sold out into early 2029. The cited basket is LITE, MRVL, AAOI, COHR, SIVE and AEHR. x.com 

ASML and Lumentum are the better way to play the EUV lithography bottleneck, as better ETFs than the new EUV ETF are likely to launch soon, even though that ETF can reach $100. ASML had to develop a way to generate extreme ultraviolet light, which does not occur naturally on Earth's surface, to make more intricate next-generation chips. Ten stocks benefit from this bottleneck, including TSMC, ASML, Lam Research, Corning and Lumentum. x.com  x.com 

The Tuttle Capital Pure Play Photonics ETF is the purest high-beta basket on the optical interconnect and photonics supply chain in US markets. It holds companies earning at least half their revenue or operating profit from photonics, spanning AI data-center optical modules, coherent optical communications, lasers, optical manufacturing and test and measurement, which is why diversified names like Nokia and Marvell are excluded. It is tiny, with about $500,000 in assets after three trading days. … Show more

Optical component stocks such as Lumentum, Coherent, Applied Optoelectronics and AXT look early in an unwind, as a wave of new photonics paid newsletters signals a crowded narrative. Price pays; narratives do not. x.com
