A cool implementation of a deep ANN using a similar system: https://arxiv.org/pdf/1610.02365.pdf

(the nonlinear units and the backprop are done on a classical computer).

The paper also points out that thermal cross-talk between the thermo-optical phase shifters can limit gate fidelities or conversely the smallest spacing between the waveguides.
