Product Demonstration

Photonect introduced 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.

One of the major roadblocks in scaling silicon photonics for commercial applications is efficient, reliable fiber-to-chip packaging. Conventional approaches often suffer from high optical loss, complex alignment, and limited scalability. In this research, we explore a promising solution: CO₂ laser fusion splicing combined with strategically designed on-chip silicon dioxide mode converters.
