1. A microwave photonics (MWP) system for performing analog signal processing, the system comprising:
a lithium niobate photonic integrated circuit (LNPIC) comprising a processing unit formed in the LNPIC and used for processing an analog electronic signal to yield at least one output optical signal, wherein the processing unit comprises:
a modulator for modulating an optical carrier signal with the analog electronic signal to yield a modulated optical signal;
a plurality of optical circuits, an individual optical circuit being arranged to receive the modulated optical signal and configured to perform an optical processing function on the modulated optical signal to generate an optical output; and
a first optical switching network for controllably routing the modulated optical signal to one or more optical circuits selected from the plurality of optical circuits to thereby controllably configure the processing unit to perform one or more respective optical processing functions of the selected one or more optical circuits, whereby one or more respective optical outputs are generated as the at least one output optical signal.
