More About OpenLight

OpenLight focuses on silicon photonics technology that integrates lasers directly onto photonic integrated circuits (PICs), targeting use cases in data communications, cloud and hyperscale data centers, telecom networks, and computing systems that require optical interconnects. Its platform is intended for enterprises, network equipment manufacturers, and system OEMs that need high-bandwidth, low-power optical links between chips, within racks, or across data center infrastructure.

The company’s offerings are positioned around a silicon photonics platform that incorporates active and passive optical components, including on-chip lasers, modulators, detectors, and waveguides, fabricated using CMOS-compatible processes (silicon photonics). By integrating lasers on the same Decentralized Inference Engine (DIE) as other photonic elements, the platform reduces the need for discrete laser components and external optical assemblies, which can simplify packaging and assembly for enterprise and telecom equipment vendors.

OpenLight participates in a foundry-based model where its photonic process design kits (PDKs) and IP blocks are made available through partner semiconductor fabs (silicon photonics / chip manufacturing). This enables enterprises and system designers to tape out custom photonic integrated circuits using standard design workflows while accessing on-chip laser capabilities. Typical architectures include co-packaged optics adjacent to switch ASICs, optical transceivers for pluggable modules, and custom PICs that interface with high-speed electrical Serializer/Deserializer (SerDes) via standard protocols.

For enterprise and cloud environments, OpenLight’s technology maps to solution categories such as high-speed interconnects for AI/ML clusters, optical transceivers for Ethernet and coherent links, and optical engines used in networking and storage fabrics (optical connectivity / data center networking). Telecom and network operators can use PICs built on its platform for metro, long-haul, or access applications that rely on Dense Wavelength Division Multiplexing (DWDM), coherent optics, or other multiplexing schemes, subject to how customers implement the IP.

The company provides design enablement in the form of IP cores, reference designs, and collaboration with ecosystem partners, which can include Electronic Design Automation (EDA) tool providers and foundries. Customers use these resources to design application-specific PICs that integrate on-chip lasers with modulators and detectors tailored to their target data rates and protocols, such as 100G, 400G, or higher-speed optical links, depending on the manufacturing process and design rules supported by the foundry. In an enterprise technology directory, OpenLight aligns with categories such as silicon photonics platforms, optical interconnect infrastructure, and photonic IP for semiconductor and system vendors.
