Returns a single ring.

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 spec.

• bend – 90 degrees bend spec.

• bend_coupler – optional bend for coupler.

• straight – straight spec.

• cross_section – cross_section spec.

• pass_cross_section_to_bend – pass cross_section to bend.
