The complex transmission vs. Fiber is also a common type of optical straight waveguide. The two orthogonal identifiers "1" and "2" with the default labels "TE" and "TM", respectively have the following definition for group index and dispersion coefficient. Hence the optical straight waveguide is always used as a phase shifter or an optical delay line.

The complex transmission vs. Fiber is also a common type of optical straight waveguide. The two orthogonal identifiers "1" and "2" with the default labels "TE" and "TM", respectively have the following definition for group index and dispersion coefficient.
Hence the optical straight waveguide is always used as a phase shifter or an optical delay line. The following figure shows the system in the example file with the straight waveguide has the properties shown on the right hand side: In the system shown above, the optical signal inputs to the first Y branch is split into two identical signals.
The waveguide in the upper branch introduces a periodic phase shift to the signal with respect to wavelengths.
The measurements of the gain and phase of the two branches are shown below. By recombining the two branches, the phase difference of signals in the two arms will construct and destruct the signal periodically with respect to wavelength frequency.
This gives an interferometer effect. The gain intensity transmission frequency response and phase of the signal outputs from the second Y branch are shown below:.

Business Need Lumotive is an innovative startup developing solid-state LIDAR for the automotive industry based on revolutionary beam-steering technology that leverages semiconductor chips designed using metamaterials and enables LIDAR systems to achieve compact size at low cost. To achieve their success in developing their lidar systems, they needed the ability to quickly and accurately model and validate the beamsteering performance of their LCM design. The most important requirement was an efficient method for predicting anisotropic permittivity and the response of the liquid crystal at the nanometer scale. This requirement created significant computational complexity for Lumotive. Their on-premise computing resource proved insufficient, so they set out for a new solution for their simulation needs. Lumotive was able to achieve their aggressive design goals with a custom workflow developed with the support of Lumerical.
