Metalens

What is a Metalens?

A metalens is a novel optical device that achieves lens functionality by controlling the phase distribution of transmitted light through surface nanostructures formed on a flat transparent substrate. Compared to conventional spherical lenses, metalenses offer the following advantages:

Ultra-thin and lightweight
Implementation of complex optical functions on a single surface (e.g., aberration correction)
Integration of multiple lenses into a single component, significantly simplifying optical systems
Applicable to a wide range of fields including smartphones, AR/VR, medical, automotive sensors, and optical communications

Principle of Functionality

Metalenses consist of numerous dielectric pillars known as meta-atoms, each with a diameter of approximately 100 to 300nm. Precise arrangement of those pillars on the substrate in a pitch within the range of the wavelength of light can locally control the speed and direction of light — realizing lens functions such as focusing or diverging light in a compact form factor.
