If processing can be performed all at once, at the same time, after processing, there is no special need other than vapor deposition of metal or multilayer films (this vapor deposition is not necessary if the polishing is done at an angle that satisfies the total reflection condition). This makes it possible to connect the optical fiber array and the photodetector array in a two-dimensional manner without requiring any additional work.
