Issue with grating coupler output port - circuit simulation in sax

[Utkarsh Saxena]

Hi,

While trying to do a circuit simulation in sax using the generic PDK of GDSFactory, I do not see the output ports of the grating couplers(type: vertical_te) in the circuit netlist, even though I am adding those ports to the circuit component using add_port(). I am able to see other optical and electrical ports. I am using gf.components.grating_coupler_elliptical().

My aim is to simulate the output of these grating couplers in the circuit.

Please let me know how I could resolve this issue.

Best,

Utkarsh
