Photonic Crystal Surface Emitting Lasers (PCSELs)

By Eulitha AG

Photonic Crystal Surface Emitting Lasers (PCSELs) shape light emissions by leveraging photonic crystals. These lasers, supported by Eulitha’s DTL technology, embed a light-emitting layer within a 2D photonic crystal pattern, enabling perpendicular light emission. This setup enhances energy efficiency, supports array fabrication, and allows beam steering without movement. Ideal for high-speed data communication, PCSELs benefit from DTL’s precision in crafting single-mode, low-energy, and high-modulation components.
