<p><span style=”font-size: 12pt;”>Hello,<\/span><\/p><p><span style=”font-size: 12pt;”>I’ve been working on a hollow core fiber simulation design and aiming to extract loss values across the 0.4 µm to 1.2 µm wavelength range, similar to the results presented in the article here: https:\/\/opg.optica.org\/optica\/fulltext.cfm?uri=optica-4-2-209&id=359511 (where they used COMSOL with finite element method).<\/span><\/p><p><span style=”font-size: 12pt;”>\"\"<\/span><\/p><p><span style=”font-size: 12pt;”>\"\"<\/span><\/p><p><span style=”font-size: 12pt;”>Currently, I’m using SiO\u2082 with a constant refractive index of 1.45. My first guess for the effective index was 0.999957. Initially, I manually created a table with the effective index values and corresponding loss results. However, I now want to perform a sweep across the entire wavelength range to obtain a more comprehensive dataset.<\/span><\/p><p><span style=”font-size: 12pt;”>\"\"<\/span><\/p><p class=”” data-start=”826″ data-end=”843″><span style=”font-size: 12pt;”>I’ve attempted:<\/span><\/p><\/p>\n
