Returns a single ring with heater on top.

ring coupler (cb: bottom) connects to two vertical straights (sl: left, sr: right), two bends (bl, br) and horizontal straight (wg: top)

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 function.

• bend – 90 degrees bend function.

• straight – straight function.

• cross_section_waveguide_heater – for 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.
