Elaser's 2Q26 EPS tripled QoQ, but the real signal is its revenue mix: AI optics jumped from 32.7% to 45.5% in seven months. COSA is the cash cow, AOC the second engine, and its biggest bet, ELSFP, is still not in volume production. STT flags the three numbers to watch next quarter.

Generative AI is driving explosive compute demand, and silicon photonics is the key to breaking transmission limits. This recap breaks down TSMC's COUPE, Elaser's ELSFP packaging, multicore fiber and automated testing to map the optical supply chain's path to volume production.
