Mzi.

Parameters:

  • delta_length – bottom arm vertical extra length.

  • length_y – vertical length for both and top arms.

  • length_x – horizontal length. None uses to the straight_x_bot/top defaults.

  • bend – 90 degrees bend library.

  • straight – straight function.

  • straight_y – straight for length_y and delta_length.

  • straight_x_top – top straight for length_x.

  • straight_x_bot – bottom straight for length_x.

  • extend_ports_straight_x – optional extend ports for straight_x_bot/top.

  • splitter – splitter function.

  • combiner – combiner function.

  • with_splitter – if False removes splitter.

  • port_e1_splitter – east top splitter port.

  • port_e0_splitter – east bot splitter port.

  • port_e1_combiner – east top combiner port.

  • port_e0_combiner – east bot combiner port.

  • nbends – from straight top/bot to combiner (at least 2).

  • cross_section – for routing (sxtop/sxbot to combiner).

  • cross_section_x_top – optional top cross_section (defaults to cross_section).

  • cross_section_x_bot – optional bottom cross_section (defaults to cross_section).

  • mirror_bot – if true, mirrors the bottom arm.

  • add_optical_ports_arms – add all other optical ports in the arms with top_ and bot_ prefix.

  • add_electrical_ports_bot – add electrical ports to the bottom arm.

  • min_length – minimum length for the straight_x_bot/top.
