An optical switching arrangement includes a plurality of input and output waveguides. Each of the input waveguides has a first plurality of 1×2 optical switches associated therewith and extending therealong. Each of the output waveguides has a second plurality of 1×2 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 1×2 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.
