“…Generally, for 𝜀 𝑧 calculation, 𝑥 𝑝𝑟𝑜𝑗 corresponds to the distance between the center of the Bragg grating and the neutral plane, defined as core offset 𝑑 (see Fig. 1 (c)) [43]- [45]. This approximation is no longer true when the distance 𝑑 is comparable or smaller than the core size of the optical waveguide.…”

A high curvature flexible Bragg grating, in planar technology, is designed, fabricated and experimentally characterized by employing silica glass. The curvature sensing mechanism for slightly off-axis core is theoretically explained and experimentally demonstrated. The electromagnetic behavior of the proposed sensor is investigated through conformal mapping, modal analysis, and coupled-mode theory. The experimental measurement reveals different sensitivities to positive and negative curvatures. The reflection spectrum of the planar Bragg grating sensor and the relationship between its resonant wavelengths and the curvature is measured for a large curvature range up to 𝟏/𝑹 = ± 𝟑𝟑𝒎 −𝟏 . The interest toward off-axis core on planar flexible platform for curvature monitoring is due to the lateral stiffness and low Young's modulus of the substrate.

“…Combined with a weaker bonding of the thermoplastic to the bare fiber, compared to a coated fiber, these voids can cause inhomogeneous stress and strain distribution across the uncoated fiber section. The longer FBG, with the grating structure being located closer to these voids, will therefore be more distorted [15]. Due to the better performance, the 3 mm long embedded FBG was used as the end mirror in the construction of the tunable fiber laser.…”

A narrow linewidth (∆λ < 0.07 nm), low noise, widely tunable Er:Yb ring fiber laser is demonstrated using a fiber Bragg grating mirror embedded in a 3D printed polymer beam. By bending the polymer beam, continuous tuning of the laser was achieved over 30 nm, from 1543 nm to 1574 nm, with power variation below 1 dB, showing high temporal and spectral stability and a signal-to-background value exceeding 50 dB. These results present a versatile and simple method for tailoring tunable narrow-linewidth lasers.

“…To date, the 3D printed contact lenses are explored in few studies available in the literature. − There are various types of 3D printing techniques being utilized for the manufacturing of optical devices, such as selective laser sintering (SLS), fused deposition modeling (FDM), , photocuring stereoscopic printing, stereolithography apparatus (SLA), and digital light printing (DLP) . Among these techniques, FDM is limited because of the low transparency of the 3D printed objects due to their thick printed layers (>0.1 mm) and the voids formed between the layers.…”

Although the manufacturing processes of contact lenses are well established, the use of additive manufacturing for their fabrication opens many new possibilities to explore. The current study demonstrates the fabrication of personalized smart contract lenses utilizing additive manufacturing. The study includes 3-dimensional (3D) modeling of contact lenses with the assistance of a computer aided designing tool based on standard commercial contact lens dimension, followed by the selection of the suitable materials and 3D printing of contact lenses. The 3D printing parameters were optimized to achieve the desired lens geometries, and a post processing treatment was performed to achieve a smooth surface finish. The study also presents functionalized contact lenses with built-in sensing abilities by utilizing microchannels at the contact lens edges. Tinted contact lenses were printed and nanopatterns were textured onto the contact lens surfaces through holographic laser ablation. 3D printed contact lenses have advantages over conventional contact lenses, offering customized ophthalmic devices and the capability to integrate with optical sensors for diagnostics.
