Aeluma's Quantum Dot Laser for Silicon Photonics Technology to be Showcased at the 2025 Optical Fiber Communications Conference (OFC)
Presentation will Highlight Groundbreaking Technology to Integrate Quantum Dot Lasers in Support of AI Infrastructure, High-Performance Computing, and Data Centers
In collaboration with AIM Photonics and UC Santa Barbara, Aeluma has co-authored a paper titled “Tunable Quantum Dot Lasers Monolithically Integrated With Silicon Photonics Rings and DBR Gratings,” that will be presented at the OFC Conference in San Francisco, California by Rosalyn Koscica, a graduate research in the group of UC Santa Barbara Professor John Bowers, on April 2 at 9:30 a.m. in Rooms 211-212.
Silicon photonics (SiPh) is being pursued aggressively by leaders in the data center, high-performance computing (HPC), and AI arenas to support high-bandwidth, low-latency, and energy-efficient interconnects. At the recent GTC AI Conference, NVIDIA announced its Spectrum-X Photonics, Co-Packaged Optics Networking Switches to Scale AI Factories to Millions of GPUs. NVIDIA’s SiPh ecosystem includes TSMC and others.
Aeluma, in collaboration with AIM Photonics and UC Santa Barbara, has been developing a scalable approach to monolithically integrate optical gain (used for lasers and amplification) directly into the AIM Photonics SiPh process. Some transceiver architectures may suffice to use a “remote laser” that is separately packaged and fiber coupled to the SiPh, however, having gain on chip is extremely beneficial in improving energy efficiency and reducing footprint. The approach being developed by Aeluma leverages a scalable approach and up to 300mm substrates. Aeluma recently announced its industry membership with AIM Photonics to accelerate development of quantum dot laser technology. The results to be presented at the OFC Conference report on promising recent results achieved in collaboration with AIM Photonics and UC Santa Barbara.
