Optical 3D sensors and augmented reality (AR) glasses are prime application examples of the rapidly growing interest in photonics‐based devices. Mobile devices are being equipped with 3D sensors for fingerprint and face recognition as well as with lidar, which is also utilized to help the navigation of autonomous vehicles. In addition, immersive AR glasses have been developed for augmented reality applications. These applications benefit from diffractive optics, whereas nanoimprint lithography (NIL) provides an affordable and reliable means to mass produce the same. The NIL‐compatible optical materials with a high refractive index presented here are proven to be pivotal in enabling the commercial breakthrough of these applications.
