Claim Text:
1. An optical circuit switch, comprising: an optical circulator configured to form N bidirectional optical beams from N input optical beams and N output optical beams, where N is an integer greater than one, each bidirectional optical beam consisting of a corresponding input optical beam from the N input optical beams and a corresponding output optical beam from the N output optical beams overlaid to follow, in opposing directions, a common optical path; a mirror array comprising at least N mirrors, the mirror array disposed to reflect each of the N bidirectional optical beams from a respective one of the at least N mirrors; and a reflector disposed to intercept bidirectional optical beams reflected from the mirror array and to reflect at least some of the intercepted bidirectional optical beams back to the mirror array.
