Polymer-Based Device Fabrication and Applications Using Direct Laser Writing Technology

Abstract

Polymer materials exhibit unique properties in the fabrication of optical waveguide devices, electromagnetic devices, and bio-devices. Direct laser writing (DLW) technology is widely used for micro-structure fabrication due to its high processing precision, low cost, and no need for mask exposure. This paper reviews the latest research progresses of polymer-based micro/nano-devices fabricated using the DLW technique as well as their applications. In order to realize various device structures and functions, different manufacture parameters of DLW systems are adopted, which are also investigated in this work. The flexible use of the DLW process in various polymer-based microstructures, including optical, electronic, magnetic, and biomedical devices are reviewed together with their applications. In addition, polymer materials which are developed with unique properties for the use of DLW technology are also discussed.

Vegetable Oil-Based Thiol-Ene/Thiol-Epoxy Resins for Laser Direct Writing 3D Micro-/Nano-Lithography

“…LDW is widely applied in polymer additive manufacturing due to its flexibility [ 2 ] and precise spatial and lateral resolution [ 3 ]. The technique is already routinely used in micro-optics, microelectronics, as well as biomedicine for the polymer-based device fabrication [ 4 ]. In polymer additive manufacturing, (meth)acrylate and epoxy monomers has been widely used for optical 3D printing (O3DP) [ 5 ].…”

STED Direct Laser Writing of 45 nm Width Nanowire

“…By numerical control the scanning route of laser beam, 2D or 3D structures with arbitrary shape can be obtained, realizing 3D printing with sub-micron resolution [11,12]. Although these micro or sub-micro structures have found applications as photonic devices [13,14], biomedical components [15,16,17], microfluidic devices [18,19,20], and electronic circuits [7,21,22], structures with nanometer feature size will find wider applications.…”

Two-Photon Polymerization: Functionalized Microstructures, Micro-Resonators, and Bio-Scaffolds

“…Negative-tone resins produced by Nanoscribe GmbH & Co. (Eggenstein-Leopoldshafen, Germany) also are applied in the TPP setups [ 61 , 62 , 63 ]. These resins, called IP Photoresins, can be used to fabricate several technological devices, such as optical elements for the biological scaffolds.…”
