Therefore, the excess noise can be lowered by thinning the multiplication layer. The layer thicknesses and doping levels of the vertical SACM APD structure can be found in Fig. IEEE Photonics Technol Lett. Light evanescent coupling schemes for waveguide photodiodes include top-to-down, down-to-top, side-coupling, and Butt-coupling, where the down-to-top coupling is the most common one for waveguide-coupled APDs owing to the CMOS compatible process and the simple structure. However, the size of the APD with a loop reflector is relatively large because of the need for long taper and big loop radius to achieve low light propagation loss. https://doi.org/10.1109/JLT.2021.3068265. Sixteenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat. from Intel proposed a recess-type waveguide-coupled SACM APD, as shown in Fig. 2019; Th3B.1:13.
