Bases: object

YBranch primitive component.

This component builds the YBranch layout cell.

Parameters:

  • name (str, optional) – Unique identifier for the device cell. Default is None.

  • xs (str, optional) – Layer or cross-section name used by the device. Default is ‘strip’.

  • w (list or np.ndarray, optional) – Width parameter in microns. Default is [1.2, 1.0, 1.8, 1.2, 1.0, 1.2, 1.2].

  • L (float, optional) – Length parameter in microns. Default is 6.

  • R_att (float, optional) – Radius parameter in microns. Default is 10.

  • A_att (float, optional) – Angle parameter in degrees. Default is 10.

  • w_port (float, optional) – Width parameter in microns. Default is 0.45.

  • show_pins (bool, optional) – Whether to draw pin markers in the generated layout. Default is False.

  • sharp_patch (bool, optional) – Whether to add geometry patches for sharp corners or cladding continuity. Default is True.

  • res (float, optional) – Value for the res parameter. Default is 0.1.
