Patent ID: 7174105

Claim:
An all-optical time division multiplexing system, comprising: a) a first divider, having a first input and a first plurality of outputs, for receiving input signals at said first input and directing said input signals to each of the outputs of said first plurality of outputs, said input signals arranged within periodic time slots; b) a second divider, having a second input and a second plurality of outputs, for receiving clock signals at said second input and directing said clock signals to each of the outputs of said second plurality of outputs; and c) a third plurality of AND gates, each having a third and a fourth input and a fifth output, for receiving said input signals at said third input from one of the outputs of said first plurality of outputs and receiving said clock signals at said fourth input from one of the outputs of said second plurality of outputs, wherein said clock signals and said input signals coincide in said third and fourth inputs of the AND gates of said third plurality of AND gates in a consecutive order to produce at said fifth output images of said input signals such that only one AND gate of said third plurality of AND gates produces at said fifth output one image of one of said input signals at each of said time slots and in a consecutive cyclic order.
