Key Points

The image filter achieves an ultra-low power consumption of 0.1mW/μm², ensuring energy efficiency while processing images.
Using a leaky ReLU function, the filter provides adaptive nonlinear functionality, enhancing existing image processing technologies.
The high-resolution capability of 1.85μm allows for detailed image analysis, which is essential for various applications.
This passive filter design uses metasurfaces, highlighting advancements in optical technology without the need for active components.

Implication

This approach demonstrates a leaky ReLU function achieving 1.85μm resolution, indicating energy-free processing with metasurfaces.

Abstract

We demonstrate a passive, all-optical image filter, achieving a leaky ReLU function with 0.1mW/μm2 thresholds and 1.85μm resolution. This filter offers an energy-free and adaptive nonlinear functionality to existing image processing.
