ubcpdk.components.ring_with_crossing(*, component: ComponentSpec = <function ebeam_crossing4_2ports>, gap: float = 0.2, length_x: float = 4, length_y: float = 0, radius: float = 5.0, coupler: ComponentSpec = <function coupler_ring>, bend: ComponentSpec = <function bend_euler_sc>, straight: ComponentSpec = <function straight>, with_component: bool = True, port_name: str = 'o4', **kwargs) → Component

Single bus ring made of two couplers (ct: top, cb: bottom) connected.

with two vertical straights (wyl: left, wyr: right) (Component Under Test) in the middle to extract loss from quality factor.

Parameters:

• component – device under test.

• gap – in um.

• length – in um.

• length_y – in um.

• radius – in um.

• coupler – coupler function.

• bend – bend function.

• with_component – True adds component. False adds waveguide.

• port_name – for component input.

• kwargs – cross_section settings.

• with_component – if False changes component for just a straight.
