si_fab.all.SiNInvertedTaper
- class si_fab.all.SiNInvertedTaper
Inverted taper on an SiN platform. Its layout and default dimensions were taken from this paper: https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/iet-opt.2018.5065
- Parameters:
- trace_template: PCell and _TraceTemplate
The trace template of the waveguide port
- name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters
The unique name of the pcell
