Vitrealab‘s core technology is the Quantum Light Chip (QLC), a photonic integrated circuit (PIC) that enables the control of laser light on the micro-scale.
Each chip contains hundreds of precisely fabricated low-loss optical waveguides interfaced with nano-imprinted micro-optics and multiple RGB laser diodes to create a uniform and collimated light source.
This polarized laser light enables an exceptionally efficient illumination of the LCoS panel. The narrow-band spectrum of laser light provides a wide color gamut, and the highly compact waveguide design inside the QLC leads to a small form factor.
The Quantum Light Chip delivers a cost-effective laser-LCoS solution without compromising on quality. The base material of the chip is a standard display glass, making the manufacturing process highly scalable.

By creating hundreds of laser beams out of a single laser diode through a three-dimensional network of waveguides, the QLC provides exceptionally bright illumination.
The combination of nanoimprinted micro-optics with our waveguides enables us to shape each laser beam individually. Collimation and direction can be customized for specific needs.
The QLC does not affect how single-mode laser diodes emit polarized light. The created laser beam array therefore emits uniformly polarized light.
The Quantum Light Chip can be manufactured in high volumes and at low cost.
The high efficiency of laser diodes in combination with the collimation and polarization allows a very efficient use of the emitted light.
The wavelengths of the applied laser diodes enable a color gamut of > 99% of Rec.2020.

Our solution is simple, cost-effective, and optimized for mass manufacturing, making it ideal for the consumer market.
Using Direct Laser Writing, we fabricate microscale optical light channels (waveguides) directly within the glass. These channels create intricate optical networks that efficiently distribute light within the chip.
Freeform microstructures provide precise control over a wide range of optical output parameters, such as beam direction and divergence angle.

What is Vitrealab’s Quantum Light Chip?
The Quantum Light Chip is a photonic integrated circuit (PIC) that combines red, green and blue (RGB) laser diodes, optical waveguides (light channels) , and nano-imprinted micro-optics to create a compact, highly efficient light source for advanced display applications.
How does the Quantum Light Chip work?
The chip uses a network of optical waveguides embedded in glass to distribute laser light from RGB laser diodes into a matrix of precisely controlled beams, delivering bright and uniform illumination.
What is laser-LCos?
Laser-LCoS (Laser-Illuminated Liquid Crystal on Silicon) is a display technology that combines the image quality and high resolution of an LCoS microdisplay with the brightness and efficiency of laser illumination.
In a laser-LCoS system, RGB laser light illuminates an LCoS panel, which acts as a reflective spatial light modulator. The LCoS panel creates the image, while the laser light provides the brightness and color needed to project it through optical systems such as combiners used in AR glasses.
Compared to conventional LED-illuminated LCoS systems, laser-LCoS can deliver higher brightness, wider color gamut, improved optical efficiency, and a smaller overall form factor. Because laser light is naturally polarized and highly directional, less light is lost within the optical path, making it particularly well suited for compact, battery-powered augmented reality devices such as AR glasses.
What are the main benefits of using laser-LCoS?
Laser-LCoS light provides exceptional brightness, energy efficiency, precise beam control, and a wider color gamut than conventional light sources, enabling vivid and accurate image reproduction.
