A universal passive logic element of positive and negative logic, made on just one transistor, is proposed. The logic element has at least two inputs, as well as three outputs: an OR, an XOR, and an ...

That’s the list. Those are your passive components. Well, it’s not that easy. Also add in a bunch of types of sensors, because they are still passive. A photoresistor is a sensor but it’s still a ...

Caulfield and Dolev's recent Nature Photonics commentary 1 provides an interesting perspective on the potential role that optics may play in the field of supercomputing. I wish to comment that there ...
