Some articles on coupling, coupling length:
... There are three aspects affect the optical coupling the distance, the coupling length and the refractive indices between the waveguide and the ... In order to optimize the coupling, it is usually the case to narrow the distance between the ring resonator and the waveguide ... The closer the distance, the easier the optical coupling happens ...
