What are Meta-Optics?

Meta-optics (metasurface optics), are a fundamentally new way to transform light with unprecedented accuracy. Gain performance and space advantages and unlock new capabilities with multifunctional meta-optics made in standard semiconductor foundries.

Metalenses: Planar Optics on a Chip

Metalenses use planar surfaces consisting of sub-wavelength structures called “nanopillars” to manipulate light and provide a degree of control not possible with traditional refractive lenses. Metasurface responses can be tuned for all properties of light including phase, wavelength, amplitude and polarization. Metalenses can combine multiple optical functions into a single element. The level of accuracy and control combined with multifunctional capability in a single surface results in a compact, optically stable module ideal for device miniaturization.

FAQs

What are the preferred wavelengths?

Currently we are focusing on production for 940nm applications

Do optical metasurfaces have AR coating?

Yes, AR coating is applied to maximize the transmission efficiency.

How do metalenses compare to a Fresnel lens?

Metalenses consist of nano-structures that create a phase-shift in light that passes through, which allows the light flow to be fully controlled in a process very similar to beam-forming. Fresnel lenses on the other hand have coarser grooved structures that bend the light that passes through according to traditional refractive/diffractive principles, providing much more limited control over the light patterns that can be created.

What is the temperature range of operation of metasurface optics?

Exceptionally large, including automotive ranges (e.g. -40°C to 110°C). Metasurfaces are inorganic materials with very low thermal expansion and very low thermal expansion mismatches, and the layering deposition process ensures no de-lamination over wide range of temperature.
