Abstract:

Acousto-optical devices (AODs) are used in optical communications systems to modulate light beam intensity, enable wavelength division multiplexing on the communications system, and also to facilitate addressing of communications channels. This paper provides a detailed discussion of solutions for the third class of applications. For the first time to our knowledge, we have developed a criterion for the spatial resolution of an addressable acousto-optical deflector that maximizes the number of communications channels while maintaining the false channel address probability to a tolerable level. We provide a theoretical demonstration and experimental confirmation of the limit on the number of possible addressable communications channels with increasing aperture of the AOD.
