The key conversion region is composed of a trident-shaped SWG in the center … WebNov 24, 2024 · Full size image. At present, there are three coupling schemes for optical fibers and waveguides in silicon photonics. The first one is called edge coupling, or in-plane coupling. The second one is called the vertical coupling, also called grating coupling or the out-plane coupling. The third one is called the prism coupling [ 1, 2 ].
