Additive manufacturing of micro optics using Two-Photon-Lithography (2PL) has been a rapidly advancing field of technology. Striving for ever more sophisticated optical systems prerequisites the access to appropriately fast and accurate wave-optical simulation methods to predict their optical performance. A simulation routine, which has been proven well suited for simulation of a vast range of 3D-printed micro optical systems, is the wave propagation method (WPM). Nevertheless, limitations in applicability remain due to the restriction on scalar electromagnetic fields, which prohibits e.g. consideration of polarization and thereby also the calculation of backwards reflection at optical interfaces. Capabilities for design and analyses are therefore impaired for 3D-printed optical systems using those properties as key features in their design. As a first step to overcome those limitations, we presented new simulation methods based on the WPM in previous publications, extending its applicability towards simulation of vector electric fields, while maintaining short simulation runtime. In the present manuscript, we focus on elaborating the practical application and integration of the previously presented simulation methods in the design of complex 3D-printed optical systems. With it, we demonstrate the consideration of polarization and backward reflections in simulations far beyond paraxial and thin element approximations.

“…The fabrication and application of surface nano- and microstructures in modern technologies of photonics opens up new opportunities in such areas as information and communication technologies [ 1 ], solar photovoltaics [ 2 ], fabrication infrared (IR) silicon photoelements [ 3 ], molecular detection in chemistry and biomedicine [ 4 ]. At the same time, the field of micro- and nano-structuring of the surface of materials under the influence of nano-, pico-, and femto-second radiation with variable energy density and exposure due to the obvious advantages of laser pulses, namely, their short duration and high peak power, is being actively explored [ 5 ].…”

Efficient Broadband Light-Trapping Structures on Thin-Film Silicon Fabricated by Laser, Chemical and Hybrid Chemical/Laser Treatments

Light-trapping structures formed on surfaces of various materials have attracted much attention in recent years due to their important role in many applications of science and technology. This article discusses various methods for manufacturing light-trapping “black” silicon, namely laser, chemical and hybrid chemical/laser ones. In addition to the widely explored laser texturing and chemical etching methods, we develop a hybrid chemical/laser texturing method, consisting in laser post-texturing of pyramidal structures obtained after chemical etching. After laser treatments the surface morphology was represented by a chaotic relief of microcones, while after chemical treatment it acquired a chaotic pyramidal relief. Moreover, laser texturing of preliminarily chemically microtextured silicon wafers is shown to take five-fold less time compared to bare flat silicon. In this case, the chemically/laser-treated samples exhibit average total reflectance in the spectral range of 250–1100 nm lower by 7–10% than after the purely chemical treatment.
