  • Isothermal, Non-Isothermal, Electro-Thermal

Steady-state, Transient, Pole-Zero & Small-Signal AC simulation

Transient Analysis

A user-specified time interval is used to compute the transient output variables in Lumerical CHARGE transient analysis section. A DC analysis can automatically determine the beginning conditions. All sources (such as power supply) that are not time-dependent are set to their DC value. Initial conditions are assumed at the start of the analysis rather than the outcome of the DC operating point analysis if Josephson junctions are present or if the UIC option is specified. All sources should start with zero output in Josephson junctions. The transient simulation can be run at each point over a variety of bias settings by combining transient analysis with a DC sweep.

Transfer Function Analysis

The AC small signal transfer function, input impedance, and output impedance of a network are calculated by Lumerical HEAT’s transfer analysis section. The DC operating point for AC analysis is automatically calculated using an operating point analysis. Moreover, the transfer function can be estimated at each point over a variety of bias circumstances by combining the transfer analysis with a DC sweep.

Pole-Zero Analysis

The poles and/or zeros in the small-signal AC transfer function are computed by the pole-zero analysis section of Lumerical CHARGE. All of the nonlinear components in the circuit’s linearized, small-signal models are then determined after the DC operating point has been calculated. The poles and zeros are then determined using this circuit. The transfer functions (output voltage)/(input voltage) and/or (output voltage)/(input current) are readily accessible for engineers to employ.

The poles and zeros of functions like input/output impedance and voltage gain can be found using these two forms of transfer functions, which cover all circumstances. With resistors, capacitors, inductors, linear-controlled sources, independent sources, BJTs, MOSFETs, JFETs, and diodes, the pole-zero analysis can be applied.

Small Signal AC Simulation

The AC output variables are calculated as a function of frequency by the AC small-signal section of Lumerical HEAT. The program initially calculates the circuit’s DC operating point before determining linearized, small-signal models for each of the circuit’s nonlinear components. The resulting linear circuit is next examined across a user-specified frequency range. Typically, a transfer function is the desired result of an AC small-signal analysis (voltage gain, transimpedance, etc). If there is just one AC input in the circuit, it is practical to set it to unity and zero phase such that the output variables have the same value as their transfer function to the input.  A DC sweep and AC analysis can then be used in tandem to perform an alternating current analysis at each position under various bias conditions.

  • Transitional 2D & 3D Modeling
  • Far-field and Grating Projections

Gaussian Beam Propagation

  • In many laser optics applications, the laser beam is taken to be Gaussian with an optimal Gaussian distribution for the irradiance profile.
  • For this reason, Lumerical DGTD has incorporated equations and other parameters that engineers will need to calculate the laser’s divergence from perfect Gaussian behavior.
  • The M2 factor, also known as the beam quality factor, contrasts a real laser beam’s performance with a diffraction-limited Gaussian beam.
  • Custom Gaussian irradiance profiles can be created using DGTD, enabling symmetry analyses around COB distances to measure directional propagation increases.

Bloch Boundary Conditions (BC’s)

  • Lumerical DGTD enables seamless phase correction when simulating a plane wave propagating at a specified angle.
  • Bloch boundary conditions are employed in a number of settings, but they are most frequently used in simulations of periodic structures illuminated by an angled plane wave source.
  • When determining the in-plane wavevector is important, Bloch Boundary Conditions (BCs) are crucial in contextualizing results.  For instance, they are routinely utilized by photonics engineers in Bandstructure computations.

Interoperable with Multiphysics Solvers

Several multiphysics simulations are offered by Ansys Lumerical DGTD in addition to other Lumerical solutions:

  • One of the main embedded solutions with Lumerical DGTD is the impact of replacement, which determines the optical loss in the mid-infrared.
  • Engineers can discover impressive low-loss performance advantages from blue-shifted interband transitions and minimum FCA through proper deployment, which is supported by linked first-principle modeling and experimental characterization.

  • Frequency Domain Reflectometry

  • Electro-Optic/Thermo-Optic Modeling
  • Waveguide Thermal Sensitivity Tuning

Frequency Domain Reflectometry (FDR)

Optically propagate a signal through a metal tine or another wave path in Ansys FEEM by seamlessly deploying oscillators. To gauge soil moisture, the difference in frequency between the output wave and the return wave is monitored.

Traditional time domain reflectometry (TDR), which is best suited for locating open and short circuit situations in conductors, may not be as sensitive to cable degradation as the FDR method due to its inherent benefits.

Because there are filtering and noise-reducing techniques in the frequency domain, for instance, FDR is less vulnerable to electrical noise and interference. Increased sensitivity and accuracy may result from this.

Additionally, since TDR pulses may have trouble moving forward after numerous noteworthy reflections, FDR analysis in FEEM is better suited for locating and describing a series of multiple deterioration episodes in lengthy cables.

 

Fourier Analysis for Signal Processing

In Ansys FEEM, The Fourier Transform and Plot/Modify Input Signal dialog boxes allow engineers to set several different functions for the x and y axes, apply different FFT windowing techniques, and set various output options.

Acting as a tool for signal decomposition for further filtration, engineers can visualize the material separation of the various signal components.  This process of bridging the gap between these two worlds (time and frequency domain) is paramount to RF engineers.

Engineers can easily apply the various Discrete Fourier Transform calculation methods using FEEM, starting with the application of the Fourier Transform, moving on to the simplified calculation technique, and concluding with the Cooley-Tukey method of the Fast Fourier Transform.

 

Spatially Varying Index Perturbations

Engineers can use the (n,k) Material import object in Ansys FEEM to transform spatially variable stress or strain into a spatially variable refractive index profile.

It is crucial to distinguish between circumstances that will cause diagonal anisotropy and those that won’t when introducing the spatially variable refractive index owing to stress or strain. Using a nk import material, which is accessible in Ansys FEEM, FDTD, and MODE, it is simple to address the diagonal anisotropy that is the focus of this example.

It will be essential to diagonalize the permittivity tensor and perform a matrix transformation to add the influence of the strain if the stress or strain produces a permittivity tensor with off-diagonal elements.  Matrix transformation makes it simple to set up the matrix transform grid properties and specific stress inputs while also providing engineers with visual assistance to help them choose the best application.

Dipole/Dipole Off-Axis Illumination

Seamless transition between on-axis and off-axis illumination is available for engineers in Ansys STACK who often toggle between multiple resolutions and proximity corrections.

One of the three main resolution-enhancement technologies, off-axis illumination (OAI), has allowed optical lithography to push the practical resolution limitations well beyond what was previously thought to be conceivable (the others being phase shifting masks and optical proximity corrections). Off-axis lighting must be properly sized and shaped for the particular mask pattern being printed in order to be used efficiently for engineers in this line of work.
