class kqcircuits.elements.airbridge_connection.AirbridgeConnection[source]

Bases: kqcircuits.elements.element.Element

The PCell declaration of an Airbridge with tapered waveguides in both ends.

build()[source]

Child classes re-define this method to build the PCell.

PCell parameters:

  • bridge_gap_width (Double) - Width of waveguide gap around the Airbridge, default=12, unit=μm

  • with_side_airbridges (Boolean) - With airbridges on the sides, default=True

  • with_right_waveguide (Boolean) - With waveguide on right side, default=True

  • gap_between_bridges (Double) - Inner distance between adjacent bridges, default=20

  • waveguide_extra (Double) - Waveguide extra length below airbridge, default=0

  • a (Double) - Width of center conductor, default=10, unit=μm

  • b (Double) - Width of gap, default=6, unit=μm

  • n (Int) - Number of points on turns, default=64

  • r (Double) - Turn radius, default=100, unit=μm

  • margin (Double) - Margin of the protection layer, default=5, unit=μm

  • face_ids (List) - Chip face IDs, list of b | t | c, default=['b', 't', 'c']

  • display_name (String) - Name displayed in GUI (empty for default), default=

  • protect_opposite_face (Boolean) - Add opposite face protection too, default=False

  • taper_length (Double) - Taper length, default=31.41592653589793, unit=μm

  • m2 (Double) - Margin of right waveguide protection layer, default=5, unit=μm

  • a2 (Double) - Non-physical value ‘-1’ means that the default size ‘a’ is used., default=20, unit=μm

  • b2 (Double) - Non-physical value ‘-1’ means that the default size ‘b’ is used., default=12, unit=μm

  • airbridge_type (String) - Airbridge type, default=Airbridge Rectangular, choices=['Airbridge Rectangular', 'Airbridge Multi Face']

  • bridge_width (Double) - Bridge width, default=20, unit=μm

  • pad_length (Double) - Pad length, default=18, unit=μm

  • bridge_length (Double) - Bridge length (from pad to pad), default=44, unit=μm
