OPTICAL ROUTING DEVICE COMPRISING HOLLOW WAVEGUIDES AND MEMSREFLECTIVE ELEMENTS

摘要

An optical routing device is described that comprises a semiconductor substrate (52) having at least one optical input (4), a plurality of optical outputs (6,8) and an array of MEMS moveable reflective elements (58;102). Th e array of moveable reflective elements (58; 102) are configurable such that light can be selectively routed from any one optical input (4) to any one of two or more of said plurality of optical outputs (6,8). Light selectively routed from any one optical input to any one of two or more of said pluralit y of optical outputs (6,8) is guided within a hollow core waveguide (54). In o ne embodiment, a cross-connect optical matrix switch is described.
