<p>Endless phase shifting apparatus, structures, and methods useful - for example - in MIMO optical demultiplexing. A first Mach-Zehnder interferometer (MZI) switch includes a phase shifter, a second MZI switch includes a phase shifter, and a line phase shifter structure optically connects the first MZI to the second MZI. The line phase shifter structure includes two waveguides, at least one of the waveguides having a phase shifter.</p> |
