“…Along this work, one further progress could be expected in the integration of the ACE component with the curved or flexible sensor arrays, which offers opportunity to realize minimized IR vision system in wafer level by eliminating the relay optics and the IR pass filter, and this is especially hopeful as conformal optics for micro‐robots. On the other hand, novel MIR/FIR (mid/far‐infrared) polymer materials could find compatibility with our proposed fabrication strategy. The ACE components with such novel materials and the arrayed detectors in corresponding spectral region could strongly promote the micro‐vision systems for MIR/FIR targeting and imaging.…”

In this work, a 3D IR artificial compound eye (ACE) optical component is fabricated using thermoplastic IR polymer material. The femtosecond laser‐assisted wet etching and the 3D nano‐imprinting techniques are proposed for fabricating this thin shell multi‐aperture component. The prepared component is close‐packed with over 1000 high‐quality micro‐facet‐lenslets (ommatidia) on the semispherical thin shell dome with base radius of 2.7 mm and sag height of 2.1 mm, enabling enlarged field of view to 148°. The ommatidia with diameter of 150 µm and numerical aperture of 0.35 are demonstrated to have a practical spatial resolution up to 160 lp mm−1. IR imaging experiments (both in passive and active scenarios) confirm its outstanding optical properties and uniformity, and demonstrate the probability of thermal target imaging with such component in the near‐infrared band. The proposed fabrication strategy shows remarkable efficiency and advantage in massive replication, and such ACE component predicts its potential in emerging applications, such as IR imaging, target tracking, and so on.

“…When refractive indices of 1.397 and 1.372 were used for the core and cladding, respectively, the crosstalk was calculated to be − 10 dB for a waveguide distance of 10 µm. To further reduce the waveguide pitch, one can employ high refractive index polymers containing inorganic nanoparticles such as ZrO 2 and TiO 2 47 , and sulfur-based polymers 48 . If the core index were increased to 1.8, the single-mode waveguide could be reduced to 0.8 × 0.6 µm 2 , and the array pitch could be reduced to 3.5 µm, preserving the low crosstalk.…”

Optical phased array (OPA) devices are being actively investigated to develop compact solid-state beam scanners, which are essential in fields such as LiDAR, free-space optical links, biophotonics, etc. Based on the unique nature of perfluorinated polymers, we propose a polymer waveguide OPA with the advantages of low driving power and high optical throughput. Unlike silicon photonic OPAs, the polymer OPAs enable sustainable phase distribution control during beam scanning, which reduces the burden of beamforming. Moreover, by incorporating a tunable wavelength laser comprising a polymer waveguide Bragg reflector, two-dimensional beam scanning is demonstrated, which facilitates the development of laser-integrated polymeric OPA beam scanners.

“…The concept of utilizing elemental sulfur (S 8 ) as an alternative feedstock for the synthesis of polymeric materials has been widely explored in the past decade . Polymeric materials derived from the polymerization of elemental sulfur constitute an intriguing new class of sulfur‐containing polymers and polysulfides, which have been referred to as chalcogenide hybrid inorganic/organic polymers (CHIPs) . One of the most widely used methods for preparing CHIPs has been the use of the inverse vulcanization process, where liquid sulfur is employed as the solvent and monomer in a homolytic ring‐opening copolymerization with organic comonomers.…”

New amine functional sulfur prepolymers were synthesized from inexpensive poly(sulfur‐random‐styrene) and 1,3‐meta‐phenylenediamine (PDA) via a proposed electrophilic aromatic substitution (SEAr) reaction. These chalcogenide hybrid inorganic/organic polymer resins show improved solubility in organic solvents. The aromatic amine functional groups were utilized to react with epoxides on polyhedral oligomeric silsesquioxanes through post‐polymerization modification which resulted in crosslinked sulfur polymers.
