Abstract:
1. An optical circuit switch, comprising: a first optical circulator configured to form a first plurality of bidirectional optical beams from a first plurality of input optical beams and a corresponding first plurality of output optical beams, each bidirectional optical beam consisting of the corresponding input optical beam and the corresponding output optical beam overlaid to follow, in opposing directions, a common optical path; a first mirror array disposed to reflect the first plurality of bidirectional optical beams; a second mirror array disposed to intercept bidirectional optical beams reflected from the first minor array and to reflect at least some of the intercepted bidirectional beams to form a second plurality of bidirectional beams; and a second optical circulator configured to separate the second plurality of bidirectional optical beams into a corresponding second plurality of input optical beams and a corresponding second plurality of output optical beams.
