Market Segmentation Analysis:
By Product
In the Silicon on Insulator (SOI) market, transceivers dominate the product segment with over 35% share in 2024. Their adoption is driven by high-speed data transmission needs across data centers and telecommunications infrastructure. Growing demand for low-power, high-bandwidth optical interconnects further strengthens transceiver adoption, particularly in hyperscale data centers. Variable optical attenuators and switches follow, supporting signal integrity and routing in dense network environments. Sensors are also gaining momentum in medical and industrial applications, though their contribution remains smaller compared to transceivers.
- For instance, ROHM’s RLD90QZW3 laser diode provides 75 W optical output at 905 nm with a 225 µm emission width for LiDAR sensing, while the RLD90QZW8 variant delivers 120 W with a 270 µm emission width for longer-range detection.
By Component
Active components lead the SOI market, holding nearly 60% share in 2024. Within this, lasers and modulators are key drivers due to their role in optical communication systems and advanced computing. Demand for efficient photodetectors further boosts growth in high-performance computing and telecommunication networks. Passive components, including filters and waveguides, support integration and signal management but capture a smaller share. The preference for active components stems from rising investment in optical interconnects and photonic integrated circuits that demand superior speed, efficiency, and scalability.
- For instance, ST’s official website and product announcements explicitly state that the platform supports bandwidths for modulators beyond 50 GHz and for photodiodes exceeding 80 GHz. This allows for the high data rates required for 800 Gbps and 1.6 Tbps solutions.
By Application
