Thank you very much Ronald!

In building blocks you basically never set the cell width directly, but possibly other parameters that may affect the cell width.

Okay so i get that.

Note that all interconnects do have a “width” keyword. Hence, if needed, adapt the interconnect to the building block pin width when connecting, e.g. with a “taper” or “ptaper”. See also here

But i dontget this. in my case above, how would i use this? i have to use the cell from demofab, not interconnects. Can you please show how could that work?

Thank you very much!

Thank you!

So if i wish to continue a waveguide from pin c1(if that is possible to do while still having external dc pin on that port), i have to use deep to shallow junctiom as well?

[AleksandarK]

So, after some more trials I managed to do this.

Here is what my code looks like now. Ideally i would like the pin and a connection to it to be similar to the one found on laser module tutorial. Anyone has any ideas?

Dear Ronald,

I added the pin, but i seem to get an error.

Here is the code.

I get:

Traceback (most recent call last):
File “dc_with_phase_shifter.py”, line 23, in <module>
demo.eopm_dc(length=150).put(C.pin[‘b0’], pin[‘c0’])
NameError: name ‘pin’ is not defined

Can anyone please help? 🙂

Thanks for the answer Ronald!

I was looking at how are lasers are made and saw how to add external pin here. I would like to add external pin to phase shifter in order to for it to be controled. How can i pass that argument to it? I understand how to do it when drawing a cell from schratch, but how to add external pin(with leads to it) when i use demo.eopm_dc() func to draw the phase shifer?

[AleksandarK]

Thank you Roland. That is helpful as well!

[AleksandarK]

Thank you very much!

That solves my problems.
