Optical Networking Stocks Drop Amid Silicon Photonics Market Uncertainty
What happened
On October 13, 2026, shares of optical networking companies experienced sharp declines due to concerns over the silicon photonics market. Ciena fell by 9.95%, while Lumentum Holdings dropped by nearly 10%. The market is currently dismissing Lumentum Holdings’ announcement from October 9 that the company had sold out of its components through 2029.

Why it matters
The steep declines reflect investor concern that if the AI sector were experiencing a bubble, demand for AI server components could plunge. This uncertainty threatens the long-term orders held by AI suppliers, potentially causing a sharp drop in revenue for firms specializing in silicon photonics.
