The year 2026 is widely expected to be a big one for optical and photonics picks-and-shovels investments.

$Applied Optoelectronics(AAOI)$  is the small-cap, high-beta transceiver name with lumpy revenue but massive AI upside if demand holds.

$Broadcom(AVGO)$  sits at the top of the stack, owning custom AI chips and networking, with its scale and pricing power already largely priced in.

$Lumentum(LITE)$  is the steady optical components leader tied to datacenters and telecom, slowly recovering margins as demand ramps up.

$Credo Technology Group Holding Ltd(CRDO)$  offers pure high-growth connectivity exposure, but its valuation already assumes near perfection.

$Astera Labs, Inc.(ALAB)$  is the early-stage optical silicon story trying to evolve into a long-term competitor to $Broadcom(AVGO)$ , backed by a large TAM narrative.

Different risk profiles, but the same structural AI buildout trade.
