Coherent and Quside Unveil Mass-Manufacturable 6-Inch VCSEL Quantum Entropy Source for Secure Encryption

COHRCOHR

Coherent and Quside demonstrated a mass-manufacturable quantum entropy source using 6-inch VCSELs, delivering high-quality randomness for cryptographic key generation and secure communications. This collaboration enables high-volume commercial deployment of quantum-safe security primitives in processors, secure elements and hardware roots of trust.

1. Earnings Release Scheduled for February 4

Coherent Corp. has confirmed it will report second quarter fiscal 2026 results for the period ended December 31, 2025, on Wednesday, February 4, immediately following New York Stock Exchange trading. The Company will host a live audio webcast at 4:30 p.m. Eastern Time to discuss performance drivers and outlook. Investors are encouraged to access the webcast via coherent.com under Investor Relations; a replay will be available within 24 hours. Management’s commentary on photonics market momentum and margin trends in datacenter and industrial end markets will be closely watched.

2. Photonics West 2026 Showcase Highlights Innovation Portfolio

At SPIE Photonics West 2026, held January 20–22 in San Francisco, Coherent will exhibit an extensive array of photonics solutions spanning continuous-wave and ultrafast lasers, beam delivery systems, advanced materials, and thermal management. Key product demonstrations include bondable diamond heat spreaders for GPU cooling with thermal conductivity exceeding 2,000 W/m·K; the Sapphire XT visible laser module optimized for super-resolution microscopy; and OCT specialty fiber assemblies engineered for sub-micron imaging in clinical devices. Live demonstrations will feature a thermo-electric generation system converting waste heat into power and a joint quantum encryption exhibit with Quside, illustrating Coherent’s push into secure data infrastructure.

3. Quantum Entropy Milestone with Quside Partnership

In collaboration with quantum technology firm Quside, Coherent has achieved a mass-manufacturable quantum entropy source using vertical cavity surface emitting lasers (VCSELs) on 6-inch wafers. This system delivers real-time, verifiable randomness for cryptographic key generation, addressing scale and cost requirements for integration into secure elements and hardware roots of trust. At Photonics West, the partners will present a live demonstration and development kits, signaling a potential new revenue stream in cybersecurity hardware. Management projects initial production readiness in mid-2026, targeting data center and defense applications that demand quantum-grade security primitives.
