Offset in Interconnects tutorial

[riseandshine]

Hi,

I have tried the interconnects tutorial and noticed a strage behavior in the Point-to-point (p2p) based interconnects section. There is an offset on the bend part.

With a message of

C:\Users\XXXX\AppData\Local\Continuum\anaconda3\lib\site-packages\nazca\mask_layers.py:147: FutureWarning: Sorting because non-concatenation axis is not aligned. A future version
of pandas will change to not sort by default.

To accept the future behavior, pass 'sort=True'.

To retain the current behavior and silence the warning, pass sort=False

  cfg.layer_table = pd.concat([cfg.layer_table, df], ignore_index=True)

Any Idea how to control the offset?

Tank you!

Dear risenandshine,

The offset is correct (intended). The warning is an unrelated warning of the pandas module in newer versions, without any consequences.

The offset is to create an optically smooth transition between the straight and bent waveguides. It is based on mode solver calculations in the waveguides on either side of the junction. You only would need to change the offset if you define your own technology from scratch.
