| Zusammenfassung: | An optical switching arrangement includes a plurality of input and output waveguides. Each of the input waveguides has a first plurality of 1x2 optical switches associated therewith and extending therealong. Each of the output waveguides has a second plurality of 1x2 optical switches associated therewith and extending therealong. Each of the first and second plurality of optical switches is selectively switchable between a through-state and a cross-state. The input and output waveguides are arranged such that optical losses arising for any wavelength of light only depend on a length of segments of the input and output waveguides located between adjacent ones of the 1x2 optical switches. Each of the first plurality of optical switches associated with each of the input waveguides is optically coupled to one of the second plurality of optical switches in a different one of the output waveguides when both optical switches are in the cross-state. |
