However, conventional metal-based photonic devices provide limited tunability and control over electromagnetic surface waves. Therefore, dynamically tunable integrated photonic devices are needed. This paper presents a theoretical model of an indium antimonide\u2013uniaxial chiral\u2013indium antimonide (InSb-UAC-InSb) structure operating in the near-infrared frequency regime. Electromagnetic wave theory is used for numerical analysis, and the characteristic equation is obtained by applying the appropriate boundary conditions. The propagation constant is examined for different values of chirality, core-width, InSb temperature, and incident-wave frequency for two types of uniaxial chiral media. Variation in temperature and chirality demonstrate the tunability of the interface under different operating conditions, enabling enhanced light confinement and low-loss propagation modes in the near-infrared region. The results show that the propagation constant in Case II exhibits greater sensitivity than that in Case I and shows a high value even at lower frequencies. This study provides a promising platform for thermally reconfigurable photonic components, temperature-sensitive optical devices, and near-infrared optical communication applications.<\/jats:p>","DOI":"10.3390\/mi17091099","type":"journal-article","created":{"date-parts":[[2026,9,21]],"date-time":"2026-09-21T08:03:47Z","timestamp":1789977827000},"page":"1099","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Temperature-Controlled Surface Plasmon Polariton Propagation in InSb\u2013Uniaxial Chiral\u2013InSb Waveguides for Near-Infrared Optical Communication"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9756-7452","authenticated-orcid":false,"given":"Bader","family":"Alhasson","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, College of Engineering in Al-Kharj, Prince Sattam bin Abdulaziz University, Al Kharj 11492, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"113001","DOI":"10.1088\/0022-3727\/45\/11\/113001","article-title":"Surface plasmon polaritons: Physics and applications","volume":"45","author":"Zhang","year":"2012","journal-title":"J.
