Abstract

With the improvement in microscopy application and industrial production technologies, many products related to optical components have been developed. Because of the commercial application, compact systems and bottom-up technologies represent the golden standard for the manufacturing of optical devices. Moreover, the use of polymeric materials combines two main advantages: reduce the fabrication cost and improve the flexibility in terms of geometry and dimension of the optical components. Recently, innovative approaches have been considered for the production of micro-lens array in a single step and one of the best candidates for the array preparation is based on the self-assembling activated onto a polymeric film. The aforementioned paradigm has been growing rapidly, representing a single step procedure that avoids the fabrication of mold and multi-steps procedures for shaping and curing the polymer material. In this framework, we present an innovative strategy for the self-assembling of polymeric micro-lens array starting from a thin polymeric film. The shaping and curing of the microstructures is guided by the pyro-electric effect activated onto a periodically poled Lithium Niobate crystal. The complete characterization of polymeric arrays of different geometries and dimension is reported as a function of the experimental conditions. Moreover, digital holography is implemented to provide the optical properties of the lenses; Based on this strategy, we performed a series experiments of lens formation controlling completely avoiding the use of electrodes, molds and costly equipment.
