Thermal Heating of a Semiconductor Saturable Absorber Mirror (SESAM)
The thermal effects of a laser beam incident on a Semiconductor Saturable Absorber Mirror (SESAM) are simulated under a range of incident beam powers.
A multiphysics simulation is performed of the saturated absorption of the beam on a SESAM, the resultant thermal heating, the structural deformation of the SESAM surface, and the effect this has on the reflected beam.
Silicon on Insulator Optical Grating Coupler
This model simulates the coupling of free-space laser radiation into waveguide modes using an optical grating coupler. The coupling efficiency and the radiation loss are calculated for different angles of incidence of the laser beam.
Topology Optimization of a Metalens
This model demonstrates how to use topology optimization to design a metalens that focuses a single wavelength to a point. Equation-based modeling is used to implement a manufacturing constraint similar to milling but with a discrete number of layers corresponding to planar processing. The results are verified on another component using an explicit geometry representation.
Reflection of a Circularly Polarized Plane Wave
In this model, a plane wave with circular polarization is reflected off an interface between air and glass. The model demonstrates three different ways of defining this problem. The first part shows how to define user-defined port mode fields. The second part uses the predefined circular polarization settings of the Port features. Finally, the last part demonstrates how the Periodic Structure feature greatly simplifies the modeling process.
Designing a Metasurface Beam Deflector Using Shape Optimization
This model is based on the existing Metasurface Beam Deflector model. The performance is improved using shape optimization by allowing both the radii and the position of the individual pillars to change.
Models updated to Demonstrate the new Outcoupling and Loss variables
The following models have been updated to demonstrate the new outcoupling, absorptance, and scattering loss variables:
Models updated to Demonstrate the Updated Polarization Plot
The Reflection of a Circularly Polarized Plane Wave, Hexagonal Grating, Hexagonal Plasmonic Color Filter, and Metasurface Beam Deflector models have been updated to demonstrate the updated polarization plots.
Models Moved to the Beam Propagation Category
The following models have been moved from the Optical Scattering to the Beam Propagation category in the Wave Optics Module Application Library:
Band-Gap Analysis of a Photonic Crystal
This model has been simplified by using the nonlinear ARPACK eigenvalue solver combined with mode filtering and following.
Fresnel Equations
The geometry in this model has been updated to be of micrometer-size, instead of meter-size.
Optically Anisotropic Waveguide
This model has been updated to use the mode following functionality available in the Mode Analysis study settings. Thereby, dispersion curves can be plotted as solid lines — one for each mode number — when modes are computed as part of a Parametric Sweep.
Scatterer on Substrate
This model demonstrates the default plots and evaluation groups added by the new Far-Field Domain, Inhomogeneous feature, the physics interfaces and the Periodic Structure and Cross Section Calculation features.
Whispering Gallery Mode Resonator
This model has been updated to demonstrate the eigenfrequency filtering functionality available in the Eigenfrequency study settings.
