RSoft Component Suite 2020

It provides powerful functions, and is designed to provide users with powerful functions, and can immediately carry out various types of optical simulation experiments and verification operations, quickly and accurately calculate and analyze, and has many analysis modules and design analysis solutions, optimization solutions, improvement of deficiencies, handling of related problems, and achieving goals.

Users can start the corresponding solution analysis communication, simulation, and CAD drawing on the software! The software supports Motivation analysis function, which can simulate and analyze LED solutions.

Since LEDs are essentially incoherent, numerical simulation of LEDs is very cumbersome. Most traditional simulation techniques are based on directly solving Maxwell equations or some derivative forms (such as Wave equations), so they cannot easily handle incoherent problems.

LED Utility can automatically use RSoft’s FullWAVE simulation software and perform all necessary pre-processing and post-processing to achieve incoherent and non-polarized light sources. Then, the utility will generate the extraction rate and radiation pattern of the LED. It also provides optical model analysis functions, which can analyze coupled waves.

Features

1. Optical model

The solar cell utility supports the following optical models:

Diffractmod, a simulation tool of RSoft, is based on rigorous coupled wave analysis (RCWA). It is suitable for use with periodic structures and provides absorption spectra that can be used in conjunction with the ideal diode electrical method described below. RSoft’s ModeProp is an eigenmode extension (EME) tool that can also be used for similar types of structures, including those with open boundaries.

Fullwave, a simulation tool of RSoft based on the finite time domain (FDTD) algorithm. It works for both periodic and non-periodic structures and provides absorption spectra or total energy density distributions, which can be used in conjunction with the ideal diode or lasermod-based methods described below, respectively.

Data files representing the absorption spectrum or total energy distribution can also be used to “bypass” this part of the calculation. This is useful for speeding up multiple simulations with the same optical properties but different electrical properties.

2. Using the AWG Utility

The AWG Utility consists of two parts: the WDM Router Layout Utility and the WDM Router Simulation Utility. The Router Layout Utility designs the input and output star couplers for simulation. It also designs two comprehensive layouts that are used only for mask export. The Router Simulation Utility creates script files that can be used to perform AWG simulations.

The simulation is performed as follows: the input star coupler is simulated using BeamProp, the program PhaseCor simulates the phase difference caused by each array arm, and then the output field of the array is used to simulate the output star coupler via BeamProp. This process is repeated at each wavelength in the spectrum to establish the wavelength response.

3. Photonic Band Theory

In principle, BandSolve can be used to discover time-independent modes of any lossless photonic structure. However, in most cases, it is intended to be applied to structures with a certain periodicity in the refractive index distribution. In fact, even when it is applied to non-periodic structures, calculations can be performed by introducing artificial periodicity. In order to correctly understand how the program works and accurately interpret its results, it is necessary to introduce some basic elements of (time-independent) electromagnetic theory in periodic structures.

4. Monitoring and Analysis

BeamProp calculates the steady-state optical field throughout the design file. It is usually useful to analyze this field in terms of standard physical quantities, such as the optical power in a specific area of ​​the circuit or the power propagated in a specific mode.

Channel monitors make these types of measurements possible. The output results are measured as a function of the propagation direction z and along the path. Monitors can be used to measure the power in the propagating field by overlap integral or power integral, measure the phase of the propagating field relative to the test field, and measure other outputs such as spot size.

5. DataBrowser

DataBrowser is a graphical utility for browsing and viewing results and images of all device-level tools in RSoft products. It can also be used to export images and animations in various standard graphical formats.

6. Diffractmod

Diffractmod computes the diffraction efficiency and field distribution of 2D or 3D periodic structures and is suitable for subwavelength structures, photonic bandgap crystals, and other grating-assisted devices. The core algorithm is based on rigorous coupled wave analysis (RCWA) and enhanced by modal transmission line (MTL) theory, which is a rigorous full-vector solver of Maxwell’s equations.

7. Gratingmod

Gratingmod is designed for a variety of applications. Gratingmod is used to design and simulate gratings that can be used in many devices. Some applications of these gratings include, but are not limited to, grating-assisted filters in WDM circuits, fiber Bragg grating devices, gain flattening devices, dispersion compensators, sidelobe suppression, and narrowband and broadband filters.

8. Lasermod

Lasermod is a photonic device design tool for simulating the optical and electronic properties of semiconductor lasers. Lasermod Lasermod combines the most versatile, easy-to-use, and easy-to-learn GUI on the market with a powerful, powerful simulation engine that provides self-consistent solutions for electrothermal transmission and optical field propagation.

Current device applications include edge-emitting (e.g., Fabry-Perot type) and vertical surface-emitting (VCSEL) lasers. Due to ongoing development work, future versions of the tool will address lasers based on DFB, SOA, and PBG cavities. Together with other component design products from RSoft Design Group, LaserMOD is well-positioned to meet the design needs of optoelectronic integrated circuits.
