Abstract:
1. An optical switching device, comprising: a. a first hollow waveguide having a cross section defined by a first core surrounded by a first enveloping wall, said first wall having a first opening; b. a second hollow waveguide having a second cross section defined by a second core surrounded by a second enveloping wall, said second wall having a second opening, said first and said second hollow waveguides positioned in a partially overlapping position defined by a common overlap of their respective said openings; c. a first light guiding lever positioned substantially in the plane of said first opening and operative to be actuated by actuating signals to assume at least one switching position in which said first lever has a curved shape, wherein said curved shape is selected from the group consisting of an S-shape and a curved arc, and d. a second light guiding lever positioned substantially in the plane of said second opening and operative to be actuated by actuating signals to synchronically assume at least one switching position essentially identical with said at least one switching position of said first light guiding lever.
