Robust, broadband, small footprint y-splitter
Join our workshop where we will perform inverse design using the adjoint optimization method to design a robust, small footprint y-splitter. We combine Lumerical’s industry leading FDTD simulator with lumopt to design a y-splitter that can be manufactured and measured at SiEPICfab.
To sign up and prepare, please:
- Register for the workshop below
- Ensure you download and install the latest version of FDTD Solutions from https://www.lumerical.com/downloads/customer
- Verify that your license is correctly installed and working in advance please!
- Necessary if you want to perform layout of your final design for submission to SiEPIC
- Install KLayout and the SiEPIC Ebeam PDK by following the instructions at https://github.com/lukasc-ubc/SiEPIC_EBeam_PDK/wiki/Installation-instructions
- Brief review of inverse design using the adjoint optimization method
- Make some design choices
- Bandwidth, number of parameters, spline boundary conditions, lithography variations
- Advanced users may want to change parameterization entirely
- Have lunch or coffee while the computer optimizes for you!
- View final S-parameter performance
- Run python script to create full gds layout in KLayout, ready to go for cutback measurements of IL
- If desired, submit design to SiEPICfab for fabrication and measurement
The attendee who creates the best design, determined by a figure of merit = min(T)* (bandwidth/100nm), where T=|S21|^2+|S31|^2, will be awarded a small prize.
