Diffractive Optical Elements
Used for beam shaping, wavefront modulation, lightweight optical systems, and multi-wavelength operations, DOE is widely applied in fields such as laser technology, virtual projection, and facial recognition.
The metasurface DOE we designed can provide 3×3 diffraction points, and the structure is designed with a graphic similar to the shape of a dog bone. This design can provide accurate and efficient optical performance, suitable for various academic research and applications.

Diffractive Optical Elements
Metasurface
Diffractive Optical Elements
Traditional DOE incorporate plastic lenses, which suffer from yellowing and heat intolerance issues. In contrast, metasurface DOE do not have these problems and are thinner than traditional DOE.
Simulating diffraction pattern distribution
DOE have been widely applied in facial recognition systems. This is a simulation of the light distribution on the face after passing through a DOE .
