Abstract

Digital Optics, especially in the form of flat wafer level optics (as with diffractive optics, computer generated holograms, holographic optical elements, MEMS and MOEMS, metasurfaces,...) are key building blocks to achieve small form factor display, imaging and sensing systems. However, flat optics do not necessarily lead to flat optical systems. Moreover, alignment of optical elements within a system can often be more costly than the optics themselves, leading to lower systems yields or to systems prone to misalignment in the field. We review here various optical architectures using wafer scale digital optics along with specific fabrication technologies that eventually lead to flat optical systems with high yields and very tight alignment features.
