Our technology

Our aluminum nitride chip platform

Uviquity builds photonic integrated circuits on aluminum nitride, the only material that carries light from the deep ultraviolet through the mid-infrared and converts it from one wavelength to another on a single semiconductor chip.

HOW IT WORKS

Why aluminum nitride works

Wide bandgap

Most semiconductors absorb ultraviolet light. AlN's wide bandgap makes it transparent down to 200 nm, so it can carry the deepest UV wavelengths on a chip.

Strong optical nonlinearity

The crystal structure natively supports second-order nonlinear optics, so light can be converted from one wavelength to another on the chip itself.

Electro-optic response

The same structure responds to electric fields — the Pockels effect — so light can be modulated and switched at high speed.

Our semiconductor platform unlocks engineered wavelengths across quantum, advanced sensing, and disinfection applications

Broad wavelength range from 200 nm to 5.5 µm on a single platform.

The platform in action: deep UV on a chip

Our chip turns blue laser light into deep UV. The complete light engine sits on a single die.

How it works

Blue Laser (458 nm)

Integrated blue semiconductor laser that emits light at 458 nm wavelength.

Wavelength tuning

Enables precision control of the wavelength of light emitted by the blue laser.

Frequency Doubling Waveguide

The waveguides double the blue laser light frequency based on a process called Second Harmonic Generation (SHG).

Deep UV light (229 nm)

Deep UV light at 229 nm wavelength is output from the chip.

Seamless integration

Uviquity’s deep UV chips integrate seamlessly into standard photonic packages.

Built to scale

Aluminum nitride belongs to the same material system as the white LED, an industry that drove dramatic cost reductions through wafer-scale manufacturing and volume production.

Uviquity's chips follow the same path: wafer-scale processing, thousands of chips per wafer, and established foundries with high-volume capacity.

Solid-state design delivers higher efficiency, smaller size, longer lifetime, and a steep cost reduction curve.

Standard photonic packaging

Uviquity's PIC is housed in industry-standard photonic packages, making our light engine ready to deploy.
