First, I have a deep etched InP waveguide cross-section with bend mode profile calculated in MODE solution. mode.lms (308.6 KB) 1. I Bend losses are propagation losses in optical fibers (or other waveguides) caused by bending. They tend to be particularly strong in large mode area fibers. Abstract: We present a novel method to fabricate low bend loss femtosecond-laser written waveguides that exploits the differential thermal stabilities of laser induced refractive index modifications. The technique consists of a two-step process; the first involves fabricating large multimode waveguides, while the second step 14 Oct 2016 Hi, I am having trouble with calculating the bend loss for a waveguide; mostly, my troubles surround the convergence of the loss to a reasonable answer.

Abstract—This paper details an accurate method for computa- tion of bending losses in rectangular optical waveguides which we combine with perturbation theory to account for the fields in the. (outer) corner regions of the guiding channel. In the case of the weakly guiding channels of interest in optical signal processing,. A rigorous, full-vectorial and computationally efficient finite-element-based modal solution, together with junction analysis and beam propagation approaches have been used to study bending loss, transition loss, mode coupling, and polarization coupling in bent optical waveguides. The waveguide offset and their widths Under the modal analysis tab, there is the option to analyze the modes of a bent waveguide for user defined radius of curvature and bend orientation. The results are those of a doughnut shaped waveguide and can be incorporated in the analysis of a bent waveguide. In this example, losses in a waveguide with one 90$
