Self-Rolled-UP Tube Base Vertical Coupler for 3D Monolithic Photonic Integration


Researchers have developed a new self-rolled-up tube based vertical photonic coupler. The technology will open up new design perspectives for semiconductor manufacturers, allowing them to integrate active and passive photonic devices with more suitable materials.

This technology provides a low loss system to integrate active and passive photonic elements. It also allows the manufacturers to utilize their existing infrastructure to produce active elements from semiconductor material, and produce passive elements from silicon, therefore it doesn't require tremendous resources to change the existing infrastructure.
