Company profile
Solinide Photonics AB is a Chalmers University spinoff based in Gothenburg, Sweden that develops silicon nitride optical microcombs for next-generation datacenter and AI infrastructure. Its microcombs are designed to replace racks of discrete lasers in co-packaged optics for AI datacentre interconnects, and the company works directly with switch, accelerator and transceiver builders to fit the comb into real architectures. The technology builds on microcomb research at Chalmers and is backed by Navigare Ventures and Chalmers Ventures. Solinide Photonics AB was founded in 2021 by photonics researchers from Chalmers University of Technology and is headquartered in Partille, Sweden. The company is a Pre-Seed business building optical-interconnect technology for AI datacenters, telecommunications networks and quantum communications. Its silicon nitride photonic approach reports greater than 60% optical conversion efficiency from CW laser light to optical combs, compared with an industry standard of 5-10%, and uses a single micro-comb photonics chip to replace multiple discrete lasers in co-packaged optics. The stated result is lower power consumption, footprint and cost at datacenter scale, while the approach combines academic research with industry validation for a path from prototype to production deployment. Current SiN processes have achieved sub-0.03 dB/cm propagation loss, Q-factors around 5 million and 28 wavelength channels above 0dBm. The team combines expertise in multilayer silicon nitride photonic circuits, nonlinear photonics and frequency-comb optics, ultrafast photonics and coherent optical communications, nanodevice fabrication, SiN-based microcomb technology, nonlinear light-matter interactions, integrated photonic-circuit design, and GaAs VCSELs for datacom.
Exhibits
For CPO integration, one pump laser and one chip provide 28 usable lines above 0 dBm, with 69% optical conversion efficiency and 100 mW total output power. This multiwavelength microcomb source is intended to provide more bandwidth per fibre at lower power per bit, with fewer components to qualify and fewer failure points to manage. Solinide Photonics AB also lists greater than 60% conversion efficiency and one-laser operation for its optical microcomb technology and CPO integration. Its MPW service provides access to a dispersion-engineered SiN platform through cost-effective MPW runs. The platform uses 750 nm thick SiN optimized for demanding dispersion-control applications and has ultra-low propagation loss. E-beam lithography enables maskless prototyping with the precision required for demanding applications and supports high design flexibility. Accelerated turnaround times are intended to support rapid design iteration and get designs to the lab sooner. The platform integrates with Luceda IPKISS for design through a measurement-validated PDK. The MPW offering is built around the same silicon nitride platform used for optical microcombs and supports prototyping of photonic designs before production deployment. The company targets optical-interconnect requirements created by AI training clusters and next-generation telecommunications networks, where traditional optical approaches cannot keep pace with bandwidth demand. Its single-chip microcomb approach is intended to reduce the number of discrete lasers while lowering datacenter-scale power consumption, footprint and cost.
