Classification accuracy, power efficiency and signal contrast comparison of MSE and SCE loss function based all-optical phase-only D2NN classifier designs with 1, 3 and 5-layers. (a) Blind testing accuracy, (b) power efficiency and (c) signal contrast analysis of the final design of fully-connected, phase-only all-optical classifiers trained for handwritten digits (MNIST). (d-f) are the same as (a-c), only the classified dataset is Fashion-MNIST instead.
