We describe the optimum telescope focal ratio for a two-element, three-surface, telecentric image-transfer microlens-to-fiber coupled integral field unit within constraints imposed by microoptics fabrication and optical aberrations. create generalized analytical description of parameters from first principles. find that performance, including all aberrations, design constrained an analytic mode...

Traditional electrical interconnections for chip-to-chip transmission have been facing several critical challenges for years [1, 2]. First, the continuing scaling down of electronic device brings a lot of problems to conventional metal interconnects -the degradation of the wire performance, the power dissipation, and the signal integrity. Second, for data transmissions between chips, the perfor...

Soft, biomimetic microlens arrays were fabricated by interference lithography from the copolymers of poly(2-hydroxyethyl methacrylate), whose hydroxyl groups were crosslinked by photoacids and external crosslinkers.

A two-dimensional/three-dimensional (2D/3D) display system is presented based on a twisted-nematic cell integrated polymeric microlens array. This device structure has the advantages of fast response time and low operation voltage. The crosstalk of the system is analyzed in detail and two approaches are proposed to reduce the crosstalk: a double lens system and the prism approach. Illuminance d...

Due to the limited numerical aperture in the beams associated with each microlens in the lenslet array (LA), a Shack – Hartmann wavefront sensor (SH/WFS) has little sensitivity to the position in depth in the object where the signal comes from. This makes the SH/WFS insensitive to depth variations of aberrations. Consequently, stray reflections from the interface optics cannot be rejected and t...

In this paper we focus on the fabrication of individual plastic refractive microlenses with Deep Lithography with Protons (DLP). We give a detailed description of the microlens fabrication technique and the calibration procedure that goes along with it. We highlight the geometrical and optical characteristics of these DLP microlenses and we demonstrate the reproducibility of the fabrication pro...
