TFLN EO modulators transform high-speed optical communication with data rates exceeding 400 Gbit/s, positioning them as essential for next-generation telecom and datacom systems. Their multi-wavelength and low-power operation across O-band, C-band, L-band, and S-band enhance DWDM system efficiency, supporting both short-distance intra-datacenter links and long-haul communication. CMOS integration enables compact, energy-efficient transceiver designs, ideal for high-port interconnects and rack-to-rack connectivity. Integrated EO polarization controllers and tunable filters further boost bandwidth and spectral efficiency, addressing the needs of modern high-performance networks.
High-Performance Computing (HPC) & AI

AI and HPC systems require unprecedented data transmission speeds, but current interconnect technologies have reached their fundamental limits. TFLN EO modulators address this challenge with ultrafast, low-power optical modulation and simplified electronics, enabling seamless GPU-to-GPU and node-to-node communication. Designed for next-generation AI and HPC architectures, TFLN integrates effortlessly with advanced packaging technologies such as co-packaged optics and 3D chip stacking. These innovations enable scalable, low-latency solutions that are critical for accelerating AI training, inference, and high-performance computing workloads.
