Abstract
A 2×2 opto-mechanical switch is disclosed. A first embodiment of the present invention utilizes a transmitting compact parallel prism and four or two pieces of the 45-degree prism to increase the beam separation. The compact parallel prism keeps a much smaller load to the relay arm. This makes the current invention less sensitive to the ambient shock and vibration. A second embodiment of the present invention utilizes a similar transmitting compact parallel prism and two wedge prisms which has similar advantages. The compact prism applies a small loading force to the relay arm. Both of these embodiments also feature superior thermal and mechanical stability. An opto-mechanical switch in accordance with the present invention utilizes a transmitting design and thus is more stable to ambient thermal or mechanical change. The embodiments of the present invention also feature much better repeatability than the conventional 2×2 optical switches.
