Additional Modules for OmniSim
In addition to the OmniSim layout editor, which includes a GDS-II exporter, a wide range of add-ons is available:
Time Domain Engines: FDTD and FETD
The FDTD (Finite-Difference Time-Domain) and FETD (Finite-Element Time-Domain) engines provide versatile time-domain simulation capabilities. FDTD offers a fast and efficient approach for modeling dielectric structures, while FETD excels in the efficient modeling of plasmonics. Both engines include 2D and 3D versions, support 64-bit and multi-core functionality, and are compatible with OmniSim and CrystalWave.
Frequency Domain Engine: FEFD Engine
A cutting-edge 2D Finite Element Frequency Domain Maxwell solver designed for the efficient propagation of electromagnetic fields in arbitrary photonic structures. This engine is compatible with OmniSim and CrystalWave and supports 64-bit and multi-core processing.
RCWA Engine
The Rigorous Coupled-Wave Analysis (RCWA) engine performs 2D and 3D simulations of light propagation through 1D- and 2D-periodic structures. It is compatible with OmniSim and CrystalWave and offers 64-bit and multi-core support.
CrystalWave Editor
A dedicated editor for photonic crystal design. When combined with OmniSim, the CrystalWave editor enables the creation of various photonic structures.
CrystalWave Band Structure Analyser (requires CrystalWave Editor)
Calculates the band structure of periodic lattices, determining band gaps and Bloch modes.
Clustered FDTD
Allows clustered FDTD simulations on Windows or Linux clusters.
Active FDTD
This module enables the modeling of active structures such as photonic crystal lasers.
Kallistos
An optimization tool integrated with most Photon Design products, designed to automatically enhance photonic device designs with minimal user input.
Photon Design Module map
This module map provides a visual overview of the Photon Design software suite, showing how the different tools connect to support your integrated photonics simulations. It starts with the core FIMMPROP module and includes key combinations such as Harold and PICWave. The size of each module indicates its relative role in the design process, while the black lines represent the data flow between components. Together, these tools form a cohesive environment for designing and optimizing photonic devices.
