“…3D printing can be ideal for customized, complex optical components. For example, opto-mechanical components [52], photonic crystal fibers and waveguides [53], gratings, and lenses [54,55] have been fabricated. 3D printing has special advantages for fabricating advanced optical components that are difficult to realize using conventional methods.…”

AbstractThree-dimensional (3D) printing is a new paradigm in customized manufacturing and allows the fabrication of complex optical components and metaphotonic structures that are difficult to realize via traditional methods. Conventional lithography techniques are usually limited to planar patterning, but 3D printing can allow the fabrication and integration of complex shapes or multiple parts along the out-of-plane direction. Additionally, 3D printing can allow printing on curved surfaces. Four-dimensional (4D) printing adds active, responsive functions to 3D-printed structures and provides new avenues for active, reconfigurable optical and microwave structures. This review introduces recent developments in 3D and 4D printing, with emphasis on topics that are interesting for the nanophotonics and metaphotonics communities. In this article, we have first discussed functional materials for 3D and 4D printing. Then, we have presented the various designs and applications of 3D and 4D printing in the optical, terahertz, and microwave domains. 3D printing can be ideal for customized, nonconventional optical components and complex metaphotonic structures. Furthermore, with various printable smart materials, 4D printing might provide a unique platform for active and reconfigurable structures. Therefore, 3D and 4D printing can introduce unprecedented opportunities in optics and metaphotonics and may have applications in freeform optics, integrated optical and optoelectronic devices, displays, optical sensors, antennas, active and tunable photonic devices, and biomedicine. Abundant new opportunities exist for exploration.

“…Many of the components commonly used to manipulate optical and microwave radiation are not readily available in the THz range [13], thus components such as optical filters, switches, and reflectors [14,15] enabling the manipulation of THz waves are of interest [12]. These components would, depending on the application, benefit from having high quality-factors (Q-factors), making them very frequency selective [14,15].…”

All-dielectric one-dimensional gratings exhibiting Fano resonances in the terahertz region

et al. 2022

View full text Add to dashboard Cite

Transmittance spectra of an all-dielectric sub-wavelength grating exhibiting Fano resonances are studied both experimentally and theoretically for a frequency interval spanning several terahertz using both s - and p -polarized radiation. Modeled spectra based on the rigorous coupled wave analysis are shown to be in good agreement with the Fourier transform of measured time-domain transmission spectra for normal and angled incidence. Finally, a model is presented that explains Fano resonance frequencies by matching the propagation constant of a discrete set of guided modes to wavenumbers that both match diffraction orders in the grating and are in a range that allows propagation in the dielectric medium.

“…Additive manufacturing technology has attracted much attention to modern three-dimensional (3D) fabrication processes due to its rapid prototyping capability, especially with a broad diversity of dielectric and metallic materials that can be used to fabricate design prototypes of almost any 3D structures. It has become even more interesting recently since it has a capability to accurately manufacture functional devices with microscale features with a good repeatability [1]- [4], which is very suitable to microfabricate functional mm-wave and THz components such as dielectric lens antennas [6]- [8], waveguides [9]- [11], sensors [9], and filters/splitters [12]- [16] for realizing low-cost complex THz systems. 3D printing techniques, normally used in mm-wave and THz technologies, are generally classified into five categories: (1) fused deposition modeling (FDM), (2) selective laser sintering (SLS), (3) stereolithographic apparatus (SLA), (4) digital-light-processing (DLP) and (5) polymer jetting (PJ).…”

Terahertz Dielectric Property Characterization of Photopolymers for Additive Manufacturing

et al. 2019

In this paper, resin-based photocurable polymer materials for stereolithography, digitallight-processing (DLP), and polymer-jetting additive manufacturing techniques were characterized from 0.2 to 1.4 terahertz (THz) for their comprehensive dielectric properties, e.g., refractive index, absorption coefficient, dielectric constant, and loss tangent, by using laser-based THz time-domain spectroscopy. A total of 14 photocurable 3D-printing polymers were chosen, owing to their suitability, in terms of printing resolution, material characteristics, and so on, for millimeter-wave (mm-wave) and THz applications. The measurement results from 0.2 to 1.4THz, the dielectric constants of all photopolymer samples under test are between 2.00-3.10, while the loss tangents are from 0.008 to 0.102, which are quite useful for many applications, e.g., 3D printed antennas and THz transmission lines, which were demonstrated by an asymptotically quasi-single-mode Bragg fiber microfabricated by DLP micromanufacturing technique using HTM140-V2 photopolymer, which is previously reported at the nominal frequencies from 0.246 to 0.276 THz.
