We observed an unexpected discrepancy in the results, specifically a sudden shift in the range L=1.6~1.8um in the Slot_Phase (derived from the angle of S in the Slot_Sweep.fsp sweep) and notable differences in Slot_dPhase1_cor (Lines 7 and 8) in RefractiveIndex_Slot.m.<\/p>\n<p style=\"margin: 0in;font-style: normal;font-weight: normal;letter-spacing: normal;text-align: start;text-indent: 0px;text-transform: none;text-decoration: none;font-family: Aptos, sans-serif;font-size: 11pt\">&nbsp;<\/p>\n<p style=\"margin: 0in;font-style: normal;font-weight: normal;letter-spacing: normal;text-align: start;text-indent: 0px;text-transform: none;text-decoration: none;font-family: Aptos, sans-serif;font-size: 11pt\">We also ran the simulations using version 2023 on Linux and encountered the same issue with this jump.<\/p>\n<p style=\"margin: 0in;font-style: normal;font-weight: normal;letter-spacing: normal;text-align: start;text-indent: 0px;text-transform: none;text-decoration: none;font-family: Aptos, sans-serif;font-size: 11pt\">&nbsp;<\/p>\n<p style=\"margin: 0in;font-style: normal;font-weight: normal;letter-spacing: normal;text-align: start;text-indent: 0px;text-transform: none;text-decoration: none;font-family: Aptos, sans-serif;font-size: 11pt\">All affected simulation points were completed 100% shown in the attached screenshot.
