Versatile route to gapless microlens arrays using laser-tunable wet-etched curved surfaces.
This work reveals a cost-efficient and flexible approach to various microlens arrays on polymers, which is essential to micro-optics elements. An 800-nm femtosecond laser is employed to control the hydrofluoric (HF) acid etching process on silica glasses, and concave microstructures with smooth curved surfaces are produced by this method. Then, the micro-structured glass templates can serve as ...
متن کاملTunable-focus microlens arrays on curved surfaces
We present a microlens array consisting of multiple liquid-based tunable-focus microlenses omnidirectionally fabricated on a hemisphere, resulting in large field of view. Polymer bridge structure is formed between microlenses to reduce the stress and deformation in each lens structure. Each microlens in the array is formed via a water-oil interface at its lens aperture. Photopatterned thermo-re...
متن کاملAngle-Etched Facet Laser Arrays (Fan Laser Arrays)
We present a novel individually addressable diode laser array that uses angle-etched facets. By arranging the lasers in a fan-like structure, all lasers emit in different directions from a common effective aperture. Using this device design, we demonstrate lasers with beam directions that are fixed and distinct, stable, single mode, and capable of simultaneous and random access operation. We an...
متن کاملPolymer network liquid crystals for tunable microlens arrays
We demonstrate a tunable-focus microlens array using polymer network liquid crystals (PNLCs). PNLCs were prepared by ultraviolet (UV) light exposure through a patterned photomask. The UV-curable monomer in each of the exposed spots forms an inhomogeneous centro-symmetrical polymer network that functions as a lens when a homogeneous electric field is applied to the cell. The focal length of the ...
متن کاملTunable microlens arrays actuated by various thermo-responsive hydrogel structures
We report on liquid-based tunable-focus microlens arrays made of a flexible polydimethylsiloxane (PDMS) polymer. Each microlens in the array is formed through an immiscible liquid–liquid interfacial meniscus. Here deionized water and silicone oil were used. The liquids were constrained in the PDMS structures fabricated through liquid-phase photopolymerization for molding and soft lithography. T...
