What Sicoya does
Sicoya GmbH is a Berlin-based semiconductor company founded in January 2015 as a spin-off of TU Berlin's silicon photonics research group (active in the field since 2007), developing highly integrated silicon photonic chipsets and optical engines for next-generation optical transceivers used in AI and hyperscale data center infrastructure. Its core product portfolio centers on the TRX-1.6T-DR8 dual-die transceiver chipset supporting 200G/400G-per-lane PAM4 operation, the RX-800G-DR4 receiver with die-stacked linear TIA, the RX-1.6T-DR4 receiver, and underlying silicon photonic dies and optical engines. The technology stack combines silicon photonic integrated circuits with high-speed SiGe BiCMOS electronics using proprietary die-stacking (Chip-on-Wafer) techniques and a node-matched-diode modulator architecture, anchored on a world-record 8-micrometer silicon modulator enabling more than 10,000 modulator units per square millimeter.
Sicoya operates a fabless hardware-sales model: it designs silicon photonic PICs and transceivers, outsources wafer manufacturing (notably to STMicroelectronics' 300mm PIC100 platform and B55X BiCMOS line), and packages products through its parent company Dawning Semi's high-volume facility in Suzhou, China. Go-to-market is enterprise-direct to international Tier 1 data center, content and service providers, alongside OEM-embedded supply of bare-die silicon and optical engines to optical transceiver vendors and network equipment manufacturers for 800GbE and 1.6TbE modules. The company is privately held, controlled by Chinese parent Dawning Semi since October 2021, and operates under the brands Sicoya-Berlin, Sicoya-China and Sicoya Global. Pricing is not publicly disclosed. Customer concentration is in a small number of Tier 1 hyperscalers and their transceiver OEMs, and the company is now positioned at the customer-sampling stage of its flagship 1.6T product.

Sicoya product offering
Product offeringCore offering
Sicoya develops and supplies highly integrated silicon photonic chipsets and optical engines for next-generation optical transceivers used in AI and hyperscale data center infrastructure. The company combines advanced silicon photonics with innovative die-stacking of electronic components to enable compact, power-efficient transceiver solutions supporting 200G and 400G per lane operation for 800GbE and 1.6TbE optical interconnects. Products are designed as components sold to optical transceiver vendors, system manufacturers, and tier 1 data center operators.
Product overview
Sicoya develops and supplies highly integrated silicon photonics chipsets for next-generation optical interconnects used in AI and hyperscale data center infrastructure. The product portfolio centers on three main silicon photonic chipset products: the TRX-1.6T-DR8 (flagship 1.6T transceiver with stacked TIA), the RX-800G-DR4 (800G receiver with die-stacked TIA), and the RX-1.6T-DR4 (1.6T receiver supporting 400G per lane). These are complemented by silicon photonic dies and optical engines that integrate transmitter and receiver functionality on photonic integrated circuits (PICs), combined with advanced chip-on-wafer (CoW) stacked electronics. The architecture supports lane rates of 200G and 400G per lane, enabling compact optical engines with high integration levels for high-speed transceivers with low power consumption and scalable manufacturing for next-generation data center networks.
