So.... might Blazar be considered quantum dot lasers? I think it's very possible. Click on link for article.

"Laser integration challenge:

Despite silicon photonics’ tremendous progress, one persistent challenge is the integration of high-performance lasers and optical gain. Some link architectures may suffice with a “remote laser” packaged separately and fiber coupled to the silicon photonics, but having on-chip optical gain is extremely beneficial when it comes to minimizing power consumption and footprint, and maximizing performance. In the pursuit of integrated optical gain, some commercially available platforms leverage flip-chip bonding of fully fabricated laser or gain chips, while others rely on bonding of wafers or chiplets followed by fabrication. These methods add complexity and cost, and are limited in scalability and achievable gain density (number of gain elements per die).

A more elegant solution is the direct epitaxial growth of laser material on silicon, which would enable integration into silicon photonics’ front-end fabrication processes. Metalorganic chemical vapor deposition (MOCVD) is emerging as the leading technique for this approach because it offers scalability and selective area growth—the ability to deposit the material selectively within patterned structures between other components. This deposition could be carried out in a similar manner to which germanium is deposited selectively for integrated photodiodes in silicon photonics."
