“…This led to large far-field divergence of the source, which complicated optical system design. A number of groups began designing and integrating simple microlens structures that were either integrated onto a substrate to be mounted on top of the microlaser arrays [23] or directly fabricated onto the microlaser devices themselves. These microlenses served to greatly reduce the divergence of the microlaser source, which has been shown to reduce the overall complexity of the optical system [24].…”

Multiscale optical design is an approach that has been successfully utilized for over 100 years by optical designers and engineers to overcome challenges and achieve desired optical system performance. The benefits of the design paradigm include improving light collection, creating specific symmetries that can be exploited, collecting additional information about the object space, partitioning the optical field to enable piecewise correction of aberrations, and alleviating packing constraints. The purpose of this paper is to review the historical emergence of the use of multiscale optical design and present key examples of developments that have expanded its capabilities over the years.

“…Ink-jet technology has been used to “write” refractive microlenses, and waveguides 28 29 using optical epoxies, with the key advantage that they can be fabricated directly onto optical components of arbitrary geometry. 30 31 32 Refractive microlens configurations which may be printed using ink-jet processes range from convex/plano hemispherical, hemi-elliptical and square 33 to convex-convex. Arrays of thousands of microlenses have been inkjet printed for use as free-space optical interconnects in VCSEL-based photonic switches, 34 with 13,872 lenslets being printed on a single wafer.…”

Applications of microfluidics and MEMS (micro-electromechanical systems) technology are emerging in many areas of biological and life sciences. Non-contact microdispensing systems for accurate, high-throughput deposition of bioactive fluids can be an enabling technology for these applications. In addition to bioactive fluid dispensing, ink-jet based microdispensing allows integration of features (electronic, photonic, sensing, structural, etc.) that are not possible, or very difficult, with traditional photolithographic-based MEMS fabrication methods. Our single fluid and multifluid (MatrixJet™) piezoelectric microdispensers have been used for spot synthesis of peptides, production of microspheres to deliver drugs/biological materials, microprinting of biodegradable polymers for cell proliferation in tissue engineering applications, and spot deposition for DNA, diagnostic immunoassay, antibody and protein arrays. We have created optical elements, sensors, and electrical interconnects by microdeposition of polymers and metal alloys. We have also demonstrated the integration of a reversed phase microcolumn within a piezoelectric dispenser for use in the fractionation of peptides for mass spectrometer analysis.

“…Next process of molding is required to fabricate the micro-optical component in mass production [8,9]. On the other hand, Microjet system technology offers by printing the number of droplets on the substrate and forming hemisphere micro-lens array by surface tension [10,11,12,13,14]. This method is simple but the unity is not uniform, its unity dependent on the apparatus precision.…”

“…This method is simple but the unity is not uniform, its unity dependent on the apparatus precision. Furthermore, fabrication of micro-lens by gray level mask were described [15], gray level mask can fabricate all shape micro-lens by design the mask pattern. However, it must need to consider the exposure dose of a photoresist to be designed, and it is too difficult.…”

Abstract. This study presents a concept to fabricate micro-lens devices using high-aspect-ratio lithography, extra-hardness electroplating, and hot embossing processes. A bath of electroplating electrolyte will be formulated to fabricate micro-optics mold inserts with extra-hardness Ni-Co alloy. It is a novel method to increase the life of the mold insert during fabricating micro-lens devices. With this high hardness, the mold inserts can resist high abrasiveness and wearness so as to extend the mold cycle life and reduce the idle time of replacing mold plates during fabrications. Therefore, the process of fabrications of micro-lens can be more cost-effective. In this study, parametric effects of reflow time, and temperature on micro-lens profiles will be characterized and discussed. Finally, the optical properties such as focal length of developed micro-lens will be measured and tested.
