A computer in which all internal circuits use light instead of electricity. Long predicted, an all-optical computer is not expected for some time as there are hurdles to overcome. However, there are ...

(Nanowerk News) By studying the theoretical limits of how light can be used to perform computation, Cornell researchers have uncovered new insights and strategies for designing energy-efficient ...

Contrary to current trends, the CPU may get bigger in the future. Yes, the size of CPUs are larger today than they were in the past, but they also pack in more transistors. The future may involve ...

IN NATURE of May 27, p. 678, Mr. A. Mallock suggests as a quantitative measure of “definition” in an optical instrument “the angular or linear size of the field of view compared with the smallest ...
