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 for coupler.

• 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.

• via_stack_offset – x,y offset for via_stack.

• with_drop – adds drop ports.
