Therefore, the control and engineering of the properties of each spatial mode is essential. Despite the multimodeness of our waveguide, the well-established Fabry-Perot technique for recording fringes in the optical transmission spectrum can successfully be employed for a detailed linear optical characterization when combined with Fourier analysis. A prerequisite for the modal sensitivity is a finely resolved transmission spectrum that ","authors_text":"B. Pressl, C. Schneider, G. Weihs, J. Ge{\\ss}ler, K. Laiho, M. Kamp, S. H\\\"ofling, T.
