Dec 04, 2017 · In this blog post, we performed qualitative analyses (modes of propagation) and quantitative analyses (dispersion curves) of the anisotropic optical waveguide using modal analysis in COMSOL Multiphysics. Diagonal anisotropy as well as off-diagonal transverse and longitudinal anisotropy were considered to derive their dispersion relationships. Prism coupling method of light coupling in waveguides is a dominant method adopted by photonic device fabricators. It is necessary to understand the effect various parameters on light coupling in such processes. We used industry standard PDE solver COMSOL Multiphysics to study and analyze the results.

Feeding a waveguide from a coaxial cable is a straightforward way to achieve electromagnetic waves inside a waveguide. Due to its small size and circular shape, the cable contributes significantly to the overall size of the problem. It is therefore necessary to keep the cable as short as possible. Simulation results are compared with formula given in5 5Marcuse, Dietrich, Curvature loss formula for optical bers, JOSA 66.3 (1976): 216-220Ashitosh V ([email protected]) Study of Bend Loss using COMSOL 13 / 19 waveguide. Figure 2. Mode simulation of trapezoidal waveguide with 6 µm height by COMSOL beam-envelope method for 1.550 µm wavelength. waveguides, and dry-film BCB with a refractive index of 1.543 is the top cladding layer. Simulation shows that the maximum of the long base for the wavelength of 1550 nm is 6.8 µm. study the optical and electrical portions of the device. The flexibility of Comsol Multiphysics makes it possible to construct unified models of EO phenomena including realistic waveguide profiles and anisotropic material properties. We demonstrate the use of the RF Module to compute both RF and optical waveguide modes

The filter is shown in Fig. 1. It is composed of a straight waveguide with small gratings engraved on one of its sides at regular intervals. At one point the distance between two of the grating teeth is increased by 50%.

Different plasmonic waveguide structures have been proposed, such as layered structures, metallic nanowires, metallic nanoparticle arrays, hybrid wedge plasmonic waveguides, and other configurations. Here, a typical plasmonic waveguide consisting of a thin film sandwiched between a cladding cover and a substrate will be considered.
