Aeluma QD Laser Advantages over Traditional EMLs
• Monolithic Integration & Scale:Unlike traditional EMLs that often require separate packaging and fiber coupling (hybrid assembly), Aeluma directly grows III-V materials (InGaAs/GaAs) on silicon, enabling on-chip, mass-market manufacturing.
• Lower Cost & Energy Efficiency:The use of 300mm silicon substrates allows for scalable, cost-effective manufacturing. Having the laser source on-chip improves energy efficiency and reduces the footprint, crucial for next-generation AI infrastructure.
• Superior Performance in Harsh Conditions: Quantum dot lasers are more temperature-stable, meaning they can operate at high temperatures (e.g., 85°C) without the heavy cooling required by traditional lasers, which is vital for co-packaged optics (CPO).
• Feedback Insensitivity: QD lasers often do not require an optical isolator, simplifying the assembly, reducing components, and lowering the bill of materials.
