Abstract

<jats:p>Up to now, there have been no commercial simulation tools accessible for researching the transmission properties of multimode microstructured optical fibers (MOFs). In order to avoid this problem, this study uses the time-independent power flow equation (TI PFE) numerical solution to examine the wavelength dependency of the equilibrium mode distribution (EMD) and steady state distribution (SSD) in multimode graded-index microstructured polymer optical fibers (GI mPOF) with a solid core. We showed that the lengths <jats:italic>z</jats:italic><jats:sub><jats:italic>s</jats:italic></jats:sub> at which an SSD is obtained in GI mPOF and the coupling length <jats:italic>L</jats:italic><jats:sub><jats:italic>c</jats:italic></jats:sub> necessary to create an EMD are shorter at λ = 568 nm than they are found to be at λ = 633 nm. The lengths <jats:italic>L</jats:italic><jats:sub><jats:italic>c</jats:italic></jats:sub> and <jats:italic>z</jats:italic><jats:sub><jats:italic>s</jats:italic></jats:sub> stay constant when the wavelength decreases further from λ = 568 to 522 and then to 476 nm. As a result, it is anticipated that a faster bandwidth enhancement in the tested GI mPOF will take place at wavelengths around λ = 568 nm as opposed to λ = 633 nm. Such a bandwidth improvement is not brought about by additional wavelength reduction. The study’s findings can be used in communication and sensory systems that use multimode GI mPOFs at different wavelengths.</jats:p>
