RVi on Choosing Optical Interconnect for AI Heterogeneous Integration

HSINCHU, June 25, 2026 — 
RVi was invited to attend the TPCA (Taiwan Printed Circuit Association) annual flagship event, the 'Advanced Trends Symposium.' Dr. Sam Ho, Co-Founder and CTO, represented the company on stage at the 'Heterogeneous Integration in the AI Era: Silicon Photonics × 3D-IC' forum to share the latest trends in optical interconnect technology for the AI era.

After sharing at TPCA's Advanced Trends Forum, RVi's view is simple: The real bottleneck in AI scale-up isn't long reach — it's the sub-100m inside the rack, where copper hits both a bandwidth and a power ceiling, yet is the hardest stretch to replace with light.

RVi doesn't see this as "VCSEL or silicon photonics." It's the right light for the right reach: silicon photonics for long reach, VCSEL as the sweet spot for short-reach scale-up — and the next step in bandwidth density is moving VCSEL from wire bonding to flip-chip. Micro-VCSEL + mass transfer + AI-based optical inspection is how RVi is making that stretch manufacturable.

Thanks to TPCA for the platform.

When Bandwidth Density Becomes the New Battleground: RVi Decodes Scale-Up Optics at the 3PHI Alliance

The AI and HPC race keeps pushing bandwidth density and power efficiency to new extremes — and the shorter the interconnect, the harder that gets! As copper hits the bandwidth ceiling and port constraints in scale-up architectures, Optical I/O isn't optional anymore. It's the inevitable path forward for next-gen semiconductors.
