ERCW PRAMs and optical communication
Theoretical Computer Science, 1996 AbstractThis paper presents algorithms and lower bounds for several fundamental problems on the Exclusive Read, Concurrent Write Parallel Random Access Machine (ERCW PRAM) and some results for unbounded fan-in, bounded fan-out (or ‘BFO’) circuits. Our results for these two models are of importance because of the close relationship of the ERCW model to ...

Waves, modes, communications, and optics: a tutorial [PDF]
Advances in Optics and Photonics, 2019 Modes generally provide an economical description of waves, reducing complicated wave functions to finite numbers of mode amplitudes, as in propagating fiber modes and ideal laser beams. But finding a corresponding mode description for counting the best orthogonal channels for communicating between surfaces or volumes, or for optimally describing the ...
