Connection to Lumerical, and Introduction to WDM - Part 2
In the previous part, we learned how to install the necessary documents for the K-Layout and numerical interconnect. In this part, we will demonstrate an example of Wavelength Division Multiplexing (WDM). You can find the resources for this example on the specified website, where you can download the necessary files and follow the instructions provided.
Overview
We will cover the following steps:
- Create a circuit layout in K-Layout.
- Show and store data in the data library.
- Connect components such as grating couplers, waveguides, and Y-branches according to the rules determined by the Process Design Kit (PDK).
- Use the Lumerical Foundry PDK and import the GDS file.
- Import the circuit netlist to the numerical interconnect.
Steps
1. Open the GDS File
First, open the GDS file. This file contains the layout of the circuit, including components like grating couplers and waveguides.
2. Circuit Layout
In the circuit layout, we have:
- Grating couplers
- Waveguides
- Y-branches
These components are connected based on the PDK rules. We use a Lumerical Foundry PDK, and we have a GDS file ready for this purpose.
3. Import to Numerical Interconnect
Next, import the circuit netlist to the numerical interconnect. Extract the file and open it. You will see the WDM setup, which includes:
- Maxenders
- Grating couplers as detectors and outputs
4. Analyze Frequency Domain
We want to analyze the frequency domain of our circuit. You can change the wiring and insert electronics as needed. The operation panel allows you to add fields, methods, and integration features.
5. Connect to Optical Network Analyzer
Load the WDL.LSF file from the downloaded folder. Name it as "top" and click OK. The numerical interconnect will show up, displaying a visualizer with four outputs representing the frequency domain of the signal:
- Input 1: Blue
- Input 2: Green
- Input 3: Red
- Input 4: Magenta
6. Update and Visualize Data
Connect the circuit with an optical network analyzer. Ensure the name "top" matches in both the K-Layout and the optical network analyzer. Extract and visualize the data. You can modify parameters, add waveguides, or other components as needed.
The purpose of this part is to connect the K-Layout to the numerical interconnect effectively.
Title: Connection to Lumerical Introduction to WDM-part 2 (Connection to Lumerical) --- In the previous part, we learned how to install the necessary software for the K layout and numerical interconnect. In this part, we will provide an example of a WDM circuit.
You can find the resources for this example on our website, where you can download the required file and follow the instructions. We will start by creating the circuit layout in the K layout, using different elements such as grading couplers, waveguides, and y branches.
We will connect the components together based on the rules determined by the PDK. In this example, we will use the Loom Foundry PDK and import the GDS file. Next, we will import the circuit netlist to the numerical interconnect. Let's open the file and extract it.
In the first system, we need to open the GDS file to see the layout. We have a grading coupler and other components in the layout. We want to analyze the frequency domain of the circuit. To do this, we will change the wiring and insert the electronics.
We can add fields, methods, and other features in the operation panel. We will then export the circuit to the netlist using ANSYS numerical circuit simulation. We can load the WDL.LSF file that we downloaded earlier.
In the K layout, we can open the LSF file and connect the circuit with an optical network analyzer. In the visualizer, we can see the frequency domain of the signal for each input. We can change the parameters and add other components as needed.
The purpose of this part is to connect the K layout to the numerical interconnect.
