Berlin's Akhetonics bags 6M to create all-optical processors - Silicon Canals
Briefly

"Many companies that claim to use 'optical computing' actually take a hybrid approach, incorporating electronics in their processing. In contrast, we are shipping a completely new, all-optical, general-purpose processor. This not only enables higher performance at lower power but also offers real-time processing that is simply not possible with electronics or opto-electronic hybrids."
"Our all-optical computing technology offers key advantages. It provides superior performance, and the ability to manufacture our processors in mature process nodes worldwide gives us a strategic advantage in the current political climate."
