A new type of processor has been developed by the researchers from the University of California, Berkeley, one that uses light in order to transmit data. Together with other universities, UC Berkeley experts have created a revolutionary, world’s first processor that fully works with light. This cutting-edge processor is much more advanced than conventional electric chips, having the ability to process 300 Gbps per square millimeter. Compared to a standard processor, that’s 10 to 50 times more data. The new chip measures 3 by 6 millimeters, and it features 2 processor cores with 70 million transistors. In addition to that, we have 850 photonic components, which are used to receive and send light.

This seems to be the interface to the external world. For a modern CPU, that's around 1000+ pin connections. Are all of those going to be replaced with optical connections? The network hardware industry would seem to be the first to gain from this. The fibre-optic cables could go straight into the message processing chips. Maybe aircraft systems could benefits from being able to replace all that copper cable with fiber-optic cable.
Corona is a 3 D many-core architecture that uses nanophotonic communication for both inter-core communication and off-stack communication to memory or I/O devices. Its peak floating-point performance is 10 teraflops. Dense wavelength division multiplexed optically connected memory modules provide 10 terabyte per second memory bandwidth. A photonic crossbar fully interconnects its 256 low-power multithreaded cores at 20 terabyte per second bandwidth.

This seems like a commercialization of the Corona Architecture PDF: pages.cs.wisc.edu...
This paper gives a good lesson in the concept of multi-unit photonic compute cores.
