Classification: CPC G | IPC G

Claim 3:
4. The apparatus of claim 2, wherein the plurality of interconnected MZIs comprises:
a first set of MZIs to perform a unitary transformation of the first array of optical signals to generate a first array of transformed optical signals; and
a second set of MZIs in optical communication with the first set of MZIs, each MZI in the second set of MZIs receiving a corresponding transformed optical signal and transmitting a first output to a nonlinearity unit,
wherein a second output of each MZI in the second set of MZIs is optically blocked so as to change a total intensity of the corresponding transformed optical signals and perform a non-unitary diagonal matrix multiplication of the corresponding transformed optical signals.
