AI Data Centers Strengthen Demand for High-Speed Optical Connectivity

The rapid expansion of AI computing is changing the requirements for data center networking. AI training and inference workloads generate substantial volumes of data between processors, switches, memory systems, and storage infrastructure. As computing density increases, network architectures must deliver high bandwidth while controlling latency, power consumption, thermal loads, and system complexity.

VCSEL-based optical interconnects are attracting attention for short-reach applications because they can support high-speed communication in compact architectures. Broadcom highlighted 200G-per-lane VCSEL and VCSEL-based NPO technologies at OFC 2026, including a 3.2T VCSEL-based NPO solution intended for AI infrastructure.

Coherent has similarly demonstrated high-speed VCSEL technologies for AI data centers. At OFC 2026, the company presented a multimode socketed CPO architecture using high-speed VCSELs, alongside other optical approaches designed to address growing bandwidth requirements.

Shift Toward VCSEL Arrays and Co-Packaged Optics

One of the most important developments shaping the VCSEL for Data Communication Market is the movement toward higher-density optical architectures. Conventional point-to-point connections can become increasingly challenging as AI systems require more parallel data movement. VCSEL arrays provide an approach for increasing optical channel density while maintaining compact packaging.

Coherent’s recent technology demonstrations illustrate this transition. At ECOC 2026, the company showcased high-density 2D VCSEL and photodiode arrays for parallel optical architectures supporting NPO and CPO applications. The company also presented a 2.3 Tbps backside-emitting VCSEL array on a silicon interposer for CPO applications.

These developments indicate that VCSEL technology is moving beyond conventional optical transceiver applications toward more tightly integrated architectures positioned closer to processors and switching components.
