Optics are everywhere, with display, imaging and communications technologies underpinning a broad range of AR / VR applications in medical, automotive, high tech and defense industries. The drive towards integration and miniaturization poses a challenge for optical elements, which can be met with emerging metalens and metasurface technology. By tailoring sub-wavelength structures on a flat surface, desired lens behavior can be implemented and unique functionality such as polarization selectivity can be enabled. The design of metalenses and metasurfaces also creates unique challenges for engineers, requiring advanced simulation tools: metalenses with billions of meta-atoms must be designed and optimized at the wavelength scale and incorporated into complex macro-scale optical systems where mechanical and thermal considerations compete with optical design requirements. Additionally, the fabrication of these lenses introduces a new paradigm, leveraging manufacturing technology commonly associated with semiconductor production. In this talk, we will explore the design and fabrication trends driving the creation of state-of-the-art metalenses and metasurfaces for AR / VR applications.

A micro-display must couple light as efficiently as possible into the capture cone defined by the AR waveguide. There is a large efficiency advantage that can be achieved by using micro-lenses over each pixel to bend more light into the capture cone, but only if the light emitters are much smaller than the micro-lens diameter. For a typical pixel pitch of ~3um, this means we want emitters ~1um. This talk with compare different ways to make very small Red pixels for use in micro-displays, including GaN, QD, and AlInGaP based approaches.

Emissive OLED-on-silicon microdisplays have been considered being opaque only so far. However, modern and advanced silicon CMOS process nodes are increasingly made on silicon-on-insulator (SOI) substrates. By separating the SOI handle wafer from the buried oxide (BOX) layer (that has the active silicon on top) and applying space-cautious layout design of the CMOS active devices as well as wiring layers it is possible to achieve semitransparent, high-resolution CMOS backplanes for microdisplays. Similar to regular OLED-on-silicon the emissive frontplane becomes embedded by wafer-level OLED post-processing. Yet, depending on pixel density and array layout a microdisplay transparency of >20% can be achieved now. Consequently, the semi-transparent microdisplay becomes the optical combiner itself, eliminating the exit pupil expander (EPE), which drastically improves the optical efficiency from the light source into the eye box.

Session 4: Materials, Processes, and Equipment for AR
For AR/VR/MR, Nanoimprinting technology is being adopted as the lithography process of choice. This is a cost-effective solution offering optimum pattern fidelity, especially for non-Manhattan/Curvilinear structures.
The pattern must be created as a 3D profile on a master, which is then used to stamp copies of them on the actual device material. This is achieved at Toppan by using the most advanced in-house owned Ebeam Lithography (EBL) fleet of equipment combined with state-of-the-art etching tools and techniques to meet the special requirements for gratings and metalens applications, for example. We will show the benefits that the well-established industry environment of photomask manufacturing brings to the ARVRMR sector. We will describe how, by using advanced semiconductor photomask imaging technology in a photomask manufacturing environment, we can deliver industrial quality grade master molds repeatedly for ARVRMR applications.
