Optical switch (70) integrated into a substrate, comprising N input channels (74-76) with N input optical free space elements (181-183), a large optical free space element (151), N input tunable optical lenses (152-154) with adjustable projection characteristic for projecting light waves received from the input optical free space elements (181-183) into the large free space element (151). The switch further comprises M output channels (190-192) with M output optical free space elements (77-79), M output tunable optical lenses (155-157) with adjustable receiving characteristic for capturing the light wave from the large free space element (151) and for feeding the light wave to the M output optical free space elements (77-79). <IMAGE> |
