Returns a double bus ring with heater on top.

two couplers (ct: top, cb: bottom) connected with two vertical straights (sl: left, sr: right)

Parameters:

  • gap – gap between bottom coupler waveguides.

  • gap_top – optional gap between top waveguides. Defaults to gap.

  • radius – for the bend and coupler.

  • length_x – ring coupler length.

  • length_y – vertical straight length.

  • coupler_ring – ring coupler spec.

  • coupler_ring_top – ring coupler spec for coupler away from vias (defaults to coupler_ring)

  • straight – straight spec.

  • bend – bend spec.

  • cross_section_heater – for heater.

  • cross_section_waveguide_heater – for waveguide with heater.

  • cross_section – for regular waveguide.

  • via_stack – for heater to routing metal.

  • port_orientation – for electrical ports to promote from via_stack. Tuple allows the left and right contacts to be defined differently.

  • via_stack_offset – x,y offset for via_stack.
