Microscale Fresnel zone plate array on flexible substrate

This paper describes microlens arrays implemented on a flexible substrate. For the first time, we have demonstrated binary Fresnel zone plates fabricated from silicon nanowires embedded in a PDMS matrix. Lens arrays on flexible substrates can potentially benefit from an increased field of view, which is important for applications such as microscopy and surveillance. Lens arrays have wide applications in 3D displays, LCD projectors, optical switches and tunable lasers. We report our design, fabrication and imaging demonstration for silicon based microlens arrays.
