In the race to scale photonic systems, coupling efficiency remains one of the most persistent bottlenecks—especially as optical I/O demands rise across datacom, sensing, and quantum platforms. At Photonect, we’re addressing this challenge head-on with our patented Mode Converter Design as a Service, purpose-built to enhance chip-level optical performance.
Why Mode Converters Matter More Than Ever
An optical fiber is as thin as a single strand of human hair. Connecting this delicate structure to a photonic chip—often with vastly mismatched optical modes—is a high-precision challenge.
The current industry standard relies on epoxy-based gluing, which is time-consuming, unstable over time, and often degrades device performance. Photonect’s solution is fundamentally different.
We introduce a SiO₂-based mode converter, designed directly into the chip layout as part of the foundry fabrication process. These mode converters are permanent, passive optical structures that act as a transitional waveguide—matching the mode size and profile between the fiber and the on-chip waveguide, dramatically reducing coupling loss.
What Sets Photonect’s Mode Converters Apart
1.Increased Coupling Efficiency
Reduce insertion loss at the fiber-chip interface, boosting overall system throughput.
2.Improved Misalignment Tolerance
Tolerate micron-level deviations in packaging—minimizing alignment overhead and increasing yield.
3.Fully Integrated in Chip Layout
Mode converters are part of the chip’s photonic design and fabricated within standard foundry processes—no post-fab additions or external components required.
4.Compatible with Fusion Splicing and Epoxy Attach
Our converters support multiple packaging approaches, including Photonect’s laser-based splicing method, which melts the fiber to the chip—glass-to-glass—eliminating the need for adhesives.
Designed for Integration. Engineered for Impact.
Photonect’s design process is not one-size-fits-all. We collaborate with your team to define optical interface specs, platform constraints, and fabrication requirements—delivering GDS-ready mode converter designs tailored to your application.
When used in conjunction with our laser-based fiber attach technology, the result is a stable, high-yield coupling solution that reduces packaging cost and complexity.
Who Should Consider This Service?
Photonic integrated circuit (PIC) designers needing robust I/O solutions
Transceiver and module manufacturers looking to optimize packaging
Research labs working on cutting-edge or non-standard platforms
System integrators seeking to scale production without coupling bottleneck
Final Word
Photonect’s Mode Converter Design as a Service is more than an optical optimization—it's a strategic enabler for next-generation photonic systems. Our SiO₂-based, foundry-ready converters give your chip a smarter interface with the outside world, improving performance, yield, and manufacturability.
Let’s make your optical connections more efficient—by design.
