Abstract: In an all optical switch an imaging system is optically coupled to the moveable micro mirrors of a MEMS device so as to produce an image of the MEMS device at the end of the imaging system which is not coupled to the MEMS device. The image is substantially in a plane with either input or output of the optical switch. The imaging system may be a telecentric system. The size of the arrangement may be reduced by compacting the optical path, e.g., using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirror. The overall system is arranged to account for any inversions introduced.
