“…A major attraction of the LIT technique is its broad material compatibility. It has been demonstrated with a variety of donor materials, including metals [32,33,[44][45][46][47][48][49][50], polymers [51,52], chalcogenides [53,54], metal oxides [55,56], and biological media [57][58][59]. In addition to the diversity of donor material, the LIT approach facilitates control over the size and shape of the transferred material, or voxel, through tuning the fluence, pulse duration, wavelength, and width of the incident laser beam [17,27,28,34].…”

AbstractThree-dimensional structure fabrication using discrete building blocks provides a versatile pathway for the creation of complex nanophotonic devices. The processing of individual components can generally support high-resolution, multiple-material, and variegated structures that are not achievable in a single step using top-down or hybrid methods. In addition, these methods are additive in nature, using minimal reagent quantities and producing little to no material waste. In this article, we review the most promising technologies that build structures using the placement of discrete components, focusing on laser-induced transfer, light-directed assembly, and inkjet printing. We discuss the underlying principles and most recent advances for each technique, as well as existing and future applications. These methods serve as adaptable platforms for the next generation of functional three-dimensional nanophotonic structures.

“…As 2 S 3 has high transparency in the IR (620 nm to 11 μm), an optical bandgap of E g = 2.35 eV ( λ = 517 nm), high refractive index ( n ∼ 2.45‐2.53), and potential for optical applications . Raman spectroscopy has shown that thermal deposition of As 2 S 3 breaks the bulk network solid into As 4 S 4 , As 4 S 6 , and S 8 molecular clusters . The As 2 S 3 films are most photosensitive if they contain a high fraction of these molecular clusters with homopolar bonds .…”

“…After exposure, a chemical etchant (usually an amine) can be used to selectively remove the unexposed material, revealing the patterned structure. Film deposition and subsequent processing has been shown to influence the size, shape, composition, durability, and optical properties of the photopatterned structures . DLW has been used to create waveguides, nanowires, woodpile and chiral gyriod photonic crystals in As 2 S 3 films .…”

Femtosecond laser induced changes and writing in optical materials have proven to be an excellent route to the production of high-quality micro-and nanofabrication of functional devices. In this paper we present the latest advancements in femtosecond laser processing of optical materials for device applications. We look at femtosecond direct laser writing for photonic device fabrication in fused silica and active glasses.We also discuss femtosecond laser writing and wet chemical etching in fused silica, Foturan, and chalcogenide glasses with applications in microfluidics, optics, sensors, and photonic devices.
