We present the use of Douglas-Gunn Alternating Direction Implicit finite difference method for computationally efficient simulation electric field propagation through a wide variety optical fiber geometries. The can accommodate refractive index profiles arbitrary shape and is implemented in tool called BPM-Matlab. validate BPM-Matlab by comparing it to published experimental, numerical, theoretical data commercially available state-of-the-art software. It user-friendly, fast, open-source....
We introduce a compact attachment for microscope objectives that allows the conversion of conventional fluorescence microscopes into Airy light-sheet microscopes. The includes one-dimensional beam generator, which comprises gradient-index collimator and 3D nano-printed cubic phase-plate, realized through two-photon polymerization nano-printing two-step writing process guarantees an optical-quality surface phase plate. micro-optical unit is affixed to mechanical holder equipped with...
Beam-shaping through optical fibers facilitates miniaturized light delivery in fields such as endoscopy, communication, etc. As the stability of beam and collection depends a lot on fiber stability, impact deformations mode-coupling for different types should be analyzed. To this end, we present numerical simulation tool modeling field propagation with arbitrary refractive index profiles, focusing twisting, tapering, bending. Our is compared against state-of-the-art software evaluating...
