Acousto-optic comparison switch for optical switching networks with analog addressing techniques.
Sorting networks based on perfect-shuffle or Banyan interconnection techniques are useful in parallel processing and telecommunications applications. An acousto-optic comparison switch that is useful in such networks is implemented, which ensures high-bandwidth optical data transmission by multiplexing the data and the address on orthogonal polarizations of light. Addresses are encoded either as the frequencies of amplitude modulation of the optical carrier or as discrete optical power levels, and are compared by using simple analog techniques. An analysis of both address techniques with respect to speed and noise is crucial to estimating the switch performance.
