In LIQUORICE we will build an operational proof-of-concept of a general-purpose programmable photonic processor. This processor is intended to provide the photonics community with a flexible rapid prototyping technology, similar in use as an electronic FPGA, to stimulate new innovation and accelerate the adoption of photonic chip technology in diverse applications, beyond the traditional photonics markets of telecom and datacom. In particular, we want to test this new photonic chip for use in programmable photonic test & measurement equipment. This is an application space where the chip’s flexibility is exceptionally useful, and which we have identified as an accessible beachhead market.
