Summary
We developed a novel light-emitting metasurface that generates and shapes laser light in one compact device. This holographic lasing system offers precise control over structured light emission for advanced photonic applications.
Area of Science:
- Photonics and optical engineering
- Metamaterials science
- Laser physics
Background:
- Light-emitting metasurfaces offer integrated light generation and beam shaping.
- Current methods struggle with precise control due to low coherence or external illumination requirements.
Purpose of the Study:
- To present a single device enabling simultaneous coherent light generation and beam shaping.
- To demonstrate holographic lasing output from an integrated metasurface and gain medium system.
Main Methods:
- Integration of a binary-structured metasurface with a gain medium.
- Utilizing holographic encoding within the metasurface structure.
- Characterization of lasing performance, threshold, and field of view.
Main Results:
- Achieved coherent light generation and precise beam shaping within a single device.
- Demonstrated robust lasing performance despite structural disorder for holographic encoding.
- Exhibited a compact, ultraflat footprint with a low lasing threshold and wide field of view.
Conclusions:
- The developed system provides a powerful platform for generating design-specified structured lasing emission.
- This technology holds significant potential for miniaturized optical systems and advanced photonic applications.
