<p>The switching system with MEMS modification of a signal wavefront implements a new type of all-optical signal switching element that uses the coherence properties of electromagnetic radiation, coupled with the materials properties of semiconductors through the application of existing Micromachined Electro-Mechanical System (MEMS) technology to provide signal switching apparatus that is faster in operation, smaller in size, more robust, and less expensive than existing signal switching elements found in all-optical communication switching systems. This is accomplished by the use of a semiconductor chip that has a MEMS mirror system implemented on its face. The MEMS device is constructed to operate in a pure materials flex mode, with no moving mechanical parts to wear. The MEMS mirror system is used to create local distortions in the reflected and/or transmitted electromagnetic radiation wavefront to redirect the electromagnetic radiation in such a way as to create channels of changed resistance in a bulk semiconductor. These changes in resistance to the channels serve to enhance or impede the motility of electrons through the bulk semiconductor, thereby providing a switching function within the bulk semiconductor. Alternatively, the redirection of the electromagnetic radiation wavefront can be effected via changes in the index of refraction in the bulk semiconductor material. <IMAGE></p> |
