Advantages of Kyomori-Ka Low-Loss Laser Coupling (L3C) Technology
Coupled light to PICs (photonic integrated circuits) remains one of the most critical challenges in silicon photonics design. At DustPhotonics, we have designed an innovative solution to this problem, which we call Low-Loss Laser Coupling (L3C). This is a patented technology that enables higher performance and scalability while reducing cost and power consumption.
L3C works by integrating off-the-shelf lasers from different manufacturers with a PIC. The benefit it brings to our customers is that it allows the supply chain to be more flexible in responding to constraints, while streamlining production.
Here are some of the most important advantages of L3C.
Higher coupling efficiency and better specification margin
L3C technology enhances the coupling between optical and photonic integrated circuits (PICs) by optimizing the interface between the laser and the silicon waveguide. Here, we use low-cost manufacturing equipment to dock and couple the laser to the PIC with sub-micron precision. L3C enables higher coupling efficiency, which we can translate into increased optical margins to meet all required PIC specifications, including output power, extinction ratio, and TDECQ (transmitter and dispersive eye diagram closure quaternion). This increases yield while reducing waste and lowering manufacturing costs.
Reduce overall system cost
Our short-range 800G-DR8 product uses a single laser to divide each channel into eight paths. This approach reduces the need for multiple lasers, which are often among the most expensive components in an optical system. Furthermore, utilizing a single laser for multiple channels reduces the number of parts and simplifies the system architecture. The end result is lower manufacturing costs, simplified inventory management, and lower overall power consumption.
Reduced Power Consumption
Reduced power consumption is another advantage of L3C technology. Improved coupling efficiency means we can use fewer lasers and/or drive each laser with lower current, thus reducing cooling requirements and ultimately enabling more energy-efficient data centers.
Operational Efficiency
By relying on off-the-shelf lasers, L3C improves operational efficiency, simplifies supply chain logistics, and rapidly scales up production without the cost and complexity of sourcing custom laser components. Furthermore, specific lasers can be difficult to procure during peak demand or periods of economic uncertainty. L3C also provides supply chain resilience during these periods by allowing the use of multiple interchangeable laser suppliers.
Compatibility with Immersion Cooling
Finally, as high-performance computing becomes increasingly energy-intensive, L3C plays a crucial role in future data centers seeking ways to manage heat. Because our L3C technology eliminates free-space gaps in the TX optical chain, we make our components compatible with immersion cooling, arguably one of the most promising methods for regulating temperature in high-performance environments.
