The VCSEL Design Tool is currently in an early adopter stage. For more information, please contact us via the contact form, or via the Ansys Innovation Space.
The VCSEL Design Tool exploits cylindrical symmetry in the optical cavity for fast and accurate computation of key laser results. In the result viewer, while cartesian axes names are reported, the results are in fact in cylindrical coordinates. This article will detail the mapping between the cartesian names and cylindrical names.
The cartesian to cylindrical mapping is set by designating the cylindrical axis in the VCSEL solver object properties. In general, the following rules are applied:
- Cartesian axis designated as the cylindrical axis is the cylindrical \(z\)-axis
- Cartesian axis that is designated as the “normal” axis in the simulation region is the cylindrical \(\phi\)-axis, as defined in the dimension settings in the Simulation Region Object
- The remaining cartesian axis is the cylindrical \(\rho\)-axis
Example
2D Sim. Region | Cylindrical Axis |
2-D Y-Normal | \(z\) |
Cartesian Axis | Cylindrical Axis |
\(x\) | \(\rho\) |
\(y\) | \(\phi\) |
\(z\) | \(z\) |
2D Sim. Region | Cylindrical Axis |
2-D X-Normal | \(y\) |
Cartesian Axis | Cylindrical Axis |
\(x\) | \(\phi\) |
\(y\) | \(z\) |
\(z\) | \(\rho\) |
