“…Although Si photonics offers numerous advantages, it is worth noting that other optical platforms, such as indium phosphide (InP) [ 10 ], gallium arsenide (GaAs) [ 11 ], lithium niobate (LiNbO 3 ) [ 12 , 13 ], and rubidium titanyl phosphate (RTP) [ 14 , 15 ], also have their own unique strengths and are preferred for certain specialized applications. The choice of platform depends on factors such as performance requirements, cost considerations, and the specific needs of the application at hand.…”
